铑精炼(refining of rhodium)

除去粗铑中的杂质，产出纯铑的过程，为铂族金属精炼组成部分。包括原料溶解、精制提纯、金属制取三部分。

原料溶解   铑难溶于酸、王水和一般溶剂，须预先将其转变成易溶状态。通常的作法是将粗铑块与锌、锡、铝、铜、镍等金属在高温熔炼成合金，铑以细粒分散于合金中；将熔融合金水碎成粒，用酸溶去贱金属，得到细铑粉；再用氯化法或硫酸氢钠熔融法，使铑生成可溶盐转入溶液。

氯化法是将铑粉和氯化钠混合，装入氯化炉中通入氯气，加温至973K温度左右氯化1～5h，铑生成可溶氯铑酸钠。

硫酸氢钠熔融法是NaHSO₄先经573K脱水，在搅拌下加入铑粉，升温至773～823K，保温2～5h，冷却后用水浸出得硫酸铑溶液。

精制提纯   将硫酸铑转变成氯配盐溶液。根据溶液中杂 质种类及含量分别采用溶剂萃取法(见铂族金属革取分离)、离子交换法(见离子交换富集铂族金属)、沉淀法或多种方法相互配合进行精制提纯。如中国用三烷基 氧化膦萃取剂萃取分离铑中的贵金属杂质，溶剂萃取和使用阳离子交换树脂的离子交换法(除贱金属杂质)相配合的精制提纯工艺，最后能制取到纯度99.99％ 的铑。沉淀法有亚硝酸钠配(络)合、五氨化法、三氨化法和亚硫酸铵法。

亚硝酸钠配(络)合法   氯铑酸盐溶液用NaOH溶液调整至pHl.5加入NaNO₂溶液，煮沸，溶液颜色由深红色变为淡黄绿色，有时近无色，铑便生成Na₃Rh(NO₂)₆。 再调整溶液至pH6～8，使铑以外的其他杂质生成氢氧化物沉淀，再经煮沸、冷却后过滤除去沉淀物。滤液加入硫化钠，使残余杂质生成硫化物沉淀。加入的硫化 钠要适量，过量会生成少量硫化铑进入沉淀物降低铑的直收率。将硫化钠沉淀物加热再过滤后，滤液加入氯化铵使铑生成(NH₄)₂NaRh(NO₂)₆白色沉淀。滤出的沉淀用盐酸溶解，溶解液浓缩赶硝后再加含盐酸的溶液制得纯氯铑酸盐溶液。如此重复上述操作，直至氯铑酸盐纯度达到要求。

反应在过量NH₄Cl中进行。将沉淀物[Rh(NH₃)₅Cl]Cl₂溶解于NaOH溶液中，杂质铱留于残渣滤出。滤液用盐酸酸化并用硝酸处理后，滤出生成的[Rh(NH₃)₅Cl](NO₃)₂溶液，将其浓缩赶硝后加入盐酸制得纯(Rh(NH₃)₅Cl]Cl₂柠檬黄色沉淀。

三氨化法   按前述的亚硝酸钠配(络)合法制取(NH₄)₂Na[Rh(NO₂)₆]沉淀，滤出的铑盐沉淀用NaOH溶液加热溶解。往过滤后的滤液中加入NH₄Cl和浓氨水，煮沸便生成[Rh(NH₃)₃(NO₂)₃]沉淀。沉淀在363～368K温度下加入盐酸至完全转变为鲜黄色的纯[Rh(NH₃)₃Cl₃]菱形结晶。

亚硫酸铵法亚硫酸铵与铑氯配离子在溶液pH6.4时生成[NH₄]₃[Rh(SO₃)₃]白色沉淀。沉淀用盐酸溶解，溶解液反复用亚硫酸铵沉淀，便能把铱除到所要求的纯度。该法对分离铑中的铂、钯、金也有效。

金属制取有氢还原和甲酸还原两种方法。

氢还原   纯铑盐低温烘干后，于773～873K温度下煅烧至NH₄Cl白烟排尽。煅烧物经冷却后转入还原炉中于1073K温度左右通氢还原，还原完毕在惰性气体(如氮气)中冷却至室温，即得金属铑粉。

甲酸还原   纯铑溶液用NaOH溶液调整至弱碱性，加热至沸，加入甲酸，便不断有铑黑生成。再调整浆液至pH7～8，煮沸，至溶液中的铑完全被还原。还原产物经冷却、过滤后，用纯水洗去铑黑中钠盐。铑黑烘干后加热通氢还原制得成品铑。

Rhodium ( /ˈroʊdiəm/ ROH-dee-əm) is a chemical element that is a rare, silvery-white, hard and chemically inert transition metal and a member of the platinum group. It has the chemical symbol Rh and atomic number 45. Naturally-occurring rhodium is composed of only one isotope, ¹⁰³Rh. It is one of the rarest precious metals and, with a price of about US$80,000/kg in 2010, is the most expensive member of that class.

Rhodium was discovered in 1803 by William Hyde Wollaston. It is found in platinum- or nickel ores together with the other members of the platinum group metals. Rhodium is mostly used as a catalyst in the three-way catalytic converter. Rhodium is inert against corrosion and most aggressive chemicals, and because of that and its rarity, rhodium is usually alloyed with platinum or palladium and applied in high-temperature and corrosion-resistive coatings. White gold is often plated with a thin rhodium layer to improve its optical impression while sterling silver is often rhodium plated for tarnish resistance. Rhodium detectors are used in nuclear reactors to measure the neutron flux level.

Rhodium (Greek rhodon (ῥόδον) meaning "rose") was discovered in 1803 by William Hyde Wollaston, soon after his discovery of palladium. He used crude platinum ore presumably obtained from South America. His procedure involved dissolving the ore in aqua regia and neutralizing the acid with sodium hydroxide (NaOH). He then precipitated the platinum by adding ammonium chloride, NH₄Cl, as ammonium chloroplatinate. Most other metals like copper, lead, palladium and rhodium were precipitated with zinc. Diluted nitric acid dissolved all but palladium and rhodium, which were dissolved in aqua regia, and the rhodium was precipitated by the addition of sodium chloride as Na₃[RhCl₆]·nH₂O. After washing with ethanol, the rose red precipitate was reacted with zinc forming rhodium metal.

After the discovery the rare element had only minor applications, for example by the turn of the century rhodium-containing thermocouples were used to measure temperatures up to 1800°C.The first major application was electroplating for decorative uses and as corrosion resistant coating. The introduction of the three way catalytic converter by Volvo in 1976 increased the demand for rhodium. The previous catalytic converters used platinum or palladium while the three way catalytic converter used rhodium to reduce the amount of NOx in the exhaust.

Rhodium is a hard, silvery, durable metal that has a high reflectance. Rhodium metal does not normally form an oxide, even when heated. Oxygen is absorbed from the atmosphere only at the melting point of rhodium, but is released on solidification. Rhodium has both a higher melting point and lower density than platinum. It is not attacked by most acids: it is completely insoluble in nitric acid and dissolves slightly in aqua regia.

Rhodium belongs to group 9 of the periodic table but has an atypical configuration in its outermost electron shells compared to the rest of the members. This can also be observed in the neighborhood of niobium (41), ruthenium (44), rhodium (45), and palladium (46).

Common oxidation states of rhodium is +3, but oxidation states from +0 to +6 are also observed.

Unlike ruthenium and osmium, rhodium forms no volatile oxygen compounds. The known stable oxides include Rh₂O₃, RhO₂, RhO₂·xH₂O, Na₂RhO₃, Sr₃LiRhO₆ and Sr₃NaRhO₆.Halogen compounds are known in nearly the full range of possible oxidation states. Rhodium(III) chloride, rhodium(IV) fluoride, rhodium(V) fluoride and rhodium(VI) fluoride are some examples. The lower oxidation states are only stable if ligands are present.

The best-known rhodium-halogen compound is the Wilkinson's catalyst chlorotris(triphenylphosphine)rhodium(I). This catalyst is used, for example, in the hydroformylation or hydrogenation of alkenes.

Naturally-occurring rhodium is composed of only one isotope, ¹⁰³Rh. The most stable radioisotopes are Rh with a half-life of 3.3 years, ¹⁰²Rh with a half-life of 207 days, ^102mRh with a half-life of 2.9 years, and ⁹⁹Rh with a half-life of 16.1 days. Twenty other radioisotopes have been characterized with atomic weights ranging from 92.926 u (⁹³Rh) to 116.925 u (¹¹⁷Rh). Most of these have half-lives shorter than an hour, except ¹⁰⁰Rh (half-life: 20.8 hours) and ¹⁰⁵Rh (half-life: 35.36 hours). There are also numerous meta states, the most stable being ^102mRh (0.141 MeV) with a half-life of about 2.9 years and ^101mRh (0.157 MeV) with a half-life of 4.34 days. (See isotopes of rhodium).

The primary decay mode before the only stable isotope, ¹⁰³Rh, is electron capture and the primary mode after is beta emission. The primary decay product before ¹⁰³Rh is ruthenium and the primary product after is palladium.

The industrial extraction of rhodium is complex as the metal occurs in ores mixed with other metals such as palladium, silver, platinum, and gold. It is found in platinum ores and extracted as a white inert metal which is very difficult to fuse. Principal sources are located in South Africa, in river sands of the Ural Mountains, and in North America, including the copper-nickel sulfide mining area of the Sudbury, Ontario region. Although the quantity at Sudbury is very small, the large amount of processed nickel ore makes rhodium recovery cost-effective. The main exporter of rhodium is South Africa (>80%) followed by Russia.The annual world production of this element is only about 25 tonnes and there are very few rhodium-bearing minerals. As of October 2007^[update], rhodium cost approximately eight times more than gold, 450 times more than silver, and 27,250 times more than copper by weight. Rhodium's typical historical price is about $1,000/troy oz, but in recent years, it has increased to about $4500/troy oz.

In 2008, the price briefly rose above $10,000 per ounce. The economic slowdown of the 3rd quarter of 2008 pushed rhodium prices sharply back below $1,000 per ounce, but they rebounded to $2,750 by early 2010 (over twice the gold price).

Main article: Synthesis of precious metals

Rhodium is a fission product of uranium-235; therefore, each kilogram of fission products contains significant amounts of the lighter platinum group metals including rhodium. Used nuclear fuel might be a possible source for rhodium. However, the extraction is complex and expensive, and the also present radioactive isotopes of rhodium would require a storage for several half-lives of the decaying isotopes in order to reduce the radioactivity. This makes this source of rhodium unattractive and no large-scale extraction has been attempted.

The primary use of this element is in automobiles as a catalytic converter, which changes harmful emissions from the engine into less polluting gases.

Cross section of a metal-core converter

In 2007, 81% of the world production of rhodium was consumed to produce three-way catalytic converters.Rhodium shows some advantages over the other platinum metals in the reduction of nitrogen oxides to nitrogen and oxygen:

2 NO_x → x O₂ + N₂

The recycling of catalytic converters also became a valuable source for rhodium. In 2007, 5.7 t were extracted from this source. Compared to the 22 t which had been mined, this is a relatively high recycling rate.

Rhodium-based catalysts are used in a number of industrial processes; notably, in the automobile catalytic converters and for catalytic carbonylation of methanol to produce acetic acid by the Monsanto process. It is also used to catalyze addition of hydrosilanes to molecular double bonds, a process important in manufacture of certain silicone rubbers. Rhodium catalysts are also used to reduce benzene to cyclohexane.

The complex of a rhodium ion with BINAP gives a widely used chiral catalyst for chiral synthesis, as in the synthesis of menthol.

Rhodium-plated white gold wedding ring

Rhodium finds use in jewelry and for decorations. It is electroplated on white gold and platinum to give it a reflective white surface. This is known as rhodium flashing in the jewelry business. It may also be used in coating sterling silver in order to strengthen the metal against tarnish, which is silver sulfide (Ag₂S) produced from the atmospheric hydrogen sulfide (H₂S). Solid (pure) rhodium jewelry is very rare, because the metal has both high melting point and poor malleability (making such jewelry very hard to fabricate) rather than due to its high price. Additionally, its high cost assures that most of its jewelry usage is in the form of tiny amounts of powder (commonly called rhodium sponge) dissolved into electroplating solutions.

Rhodium has also been used for honors, or to symbolize wealth, when more commonly used metals such as silver, gold or platinum are deemed insufficient. In 1979, the Guinness Book of World Records gave Paul McCartney a rhodium-plated disc for being history's all-time best-selling songwriter and recording artist.

Many opponents of fiat money advocate the use of rhodium in high-value coins. The Free Competition in Currency Act sponsored by United States Representative Ron Paul would legalize private minting of rhodium, among other precious metals.

Rhodium foil and wire

Rhodium is used as an alloying agent for hardening and improving the corrosion resistance of platinum and palladium. These alloys are used in furnace windings, bushings for glass fiber production, thermocouple elements, electrodes for aircraft spark plugs, and laboratory crucibles. Other uses include:

• An electrical contact material due to its low electrical resistance, low and stable contact resistance, and high corrosion resistance.
• Plated rhodium, made by electroplating or evaporation, is extremely hard and is used for optical instruments.

• It is also used as a filter in mammography systems because of the characteristic X-rays it produces.

• Rhodium is also used to coat some parts of high-quality fountain pens due to its high reflectance, as well as it's chemical and mechanical resistance. These pens include Graf von Faber-Castell^[42] and Caran D'ache.

• Rhodium neutron detectors are used in Combustion Engineering Nuclear Reactors to measure neutron flux levels – a method that requires a digital filter to determine the current neutron flux level, as there are three signals generated: immediate, a few seconds later, and a minute later, each with its own signal level, and all three are combined in the rhodium detector signals. The three Palo Verde nuclear reactors each have 305 rhodium neutron detectors, 61 detectors on each of 5 vertical levels, providing an accurate 3-D "picture" of reactivity and allowing fine tuning to most economically burn the nuclear fuel.

Being a noble metal, pure rhodium is inert. However, chemical complexes of rhodium can be reactive. Median lethal dose (LD₅₀) for rats is 12.6 mg of rhodium chloride (RhCl₃) per kilogram of body weight.^[45] Rhodium compounds can strongly stain human skin. The element plays no biological role in humans. If used in elemental form rather than as compounds, the metal is harmless.

发现人：武拉斯顿    发现年代：1803~1804年
发现过程：1803~1804年，英国的武拉斯顿，在提炼钯铂的废渣的玫瑰色盐里发现有铑的存在。

铑-元素描述

银白色金属，质极硬，耐磨，也有相当的延展性。密度12.4克/厘米3。熔点1966±3℃，沸点3727±100℃。化合价2、4和6。第一电离能7.46电子伏特。在中等的

蓝色仿钻镀铑戒指温度下，它也能抵抗大多数普通酸（包括王水在内）。在200~600℃可与热浓硫酸、热氢溴酸、次氯酸钠和游离卤素起化学反应。不与许多熔融金属，如金、银、钠和钾以及熔融的碱起反应。
元素来源：存在于铂矿中，在精炼过程中可以集取而制得。
元素用途：可用来制造加氢催化剂、热电偶、铂铑合金等。也常镀在探照灯和反射镜上。还用来作为宝石的加光抛光剂和电的接触部件。
元素辅助资料：
铑属铂系元素。铂系元素几乎完全成单质状态存在，高度分散在各种矿石中，例如原铂矿、硫化镍铜矿、磁铁矿等。铂系元素几乎无例外地共同存在，形成天然合金。在含铂系元素矿石中，通常以铂为主要成分，而其余铂系元素则因含量较小，必须经过化学分析才能被发现。由于锇、铱、钯、铑和钌都与铂共同组成矿石，因此它们都是从铂矿提取铂后的残渣中发现的。它们中除铂和钯外，不但不溶于普通的酸，而且不溶于王水。铂很易溶于王水，钯还溶于热硝酸中。所有铂系元素都有强烈形成配位化合物的倾向。

铑-发现

1803到1804年，在武拉斯顿发现钯不久，他将天然铂矿溶解在王水中，加入氢氧化钠溶液，中和过剩的酸，再加入氯化铵（NH4Cl），使铂沉淀为铂氯化铵（(NH4)2[PtCl4]），再加入氰化汞，使钯沉淀为氰化钯，滤去沉淀后，往滤液中加入盐酸，除去过量的氰化汞，并把溶液蒸发至干，

氯化铑出现一种暗红色沉淀，分析证明是由一种新金属和钠的氯化物形成的盐Na3RhCl6?18H2O。因这种新金属的具有玫瑰的艳红色，就以希腊文中玫瑰rhodon命名它为rhodium。

铑是一种类似于铝的青白色金属，质硬而脆，具有较强的反射能力，加热状态下特别柔软。铑的化学稳定性好。铑的抗氧化性很好，在空气中能长期保持光泽。在高温下铑与氧气作用生成挥发性的氧化物，增加它的蒸发速度。但铑在加热时会蒙上一层黑色氧化膜，而当温度超过1200℃时氧化膜会消失。铑对酸(浓硫酸除外)、王水、以及硫、氯和氟的耐腐蚀性较高。铑的高温强度很好，但冷塑性加工性能稍差。

铑是由英国化 学家威尔亚姆.沃尔拉斯统(William Hyde Wollaston)于1803年发现的。他是在发现钯后很快就发现了铑。沃尔拉斯统先是把粗铂溶解于王水中，然后用苛性纳NaOH中和过剩的酸，并从中 和溶液中沉积出了含氯化铵的铂和含氰化汞的钯，之后将滤渣用盐酸处理，为避免氰化汞过剩，要使其干透。用酒精处理过的残渣乃是呈现为深红色的铑盐与钠盐粉 未，将这种粉未在氢气流中加热便可产出铑。铑由镍生产的副产品获得。亦可在铂矿中发现，在一些铂合金中用作催化剂。

铑-主要用途

铑的主要用途是用作高质量科学仪器的防磨涂料和催化剂，铑铂合金用于生产热电偶。也用于镀在车前灯反射镜，电话中继器，钢笔尖等。

汽车制造业是铑的最大用户。目前汽车制造业中铑的主要用途

珍珠母贝镀铑戒指是汽车尾气催化剂。其它消耗铑的工业部门是玻璃制造业，镶牙合金制造业，珠宝制品业。而随着燃料电池技术的不断发展和燃料电池汽车技术的逐步成熟，汽车工业的用铑量将持续增加。

铂族金属和合金有很多重要的工业用途。过去主要是制造蒸馏釜以浓缩铅室法制得稀硫酸，也曾用铂铱合金制造标准的米尺和砝码。在19世纪中叶，俄国曾制造铂铱合金币在市场上流通。目前，铂族金属及其合金的主要用途为制造催化剂。铂铑合金对熔融的玻璃具有特别的抗蚀性，可用于制造生产玻璃纤维的坩埚。铂铱、铂铑、铂钯合金有很高的抗电弧烧损能力，被用作电接点合金，这是铂的主要用途之一。

由于铂化学性质稳定，纯铂、铂铑合金或铂铱合金制造的实验器皿如坩埚、电极、电阻丝等是化学实验室的必备物。铂钴合金是一种可加工的磁能积高的硬磁材料。铂和铂合金广泛用于制造各种首饰特别是镶钻石的戒指、表壳和饰针。铂或钯的合金也可作牙科材料。铂、钯和铑可作电镀层，常用于电子工业和首饰加工中。近年来涂钌和铂的钛阳极代替了电解槽中的石墨阳极，提高了电解效率，并延长电极寿命，是氯碱工来中一项重要的技术改进，为钌在工业上使用开辟了新途径。锇铱合金可制造笔尖和唱针。钯合金还用于制造氢气净化材料和高温钎焊焊料等。在化学工业中还使用包铂设备。

隨著各種電子產品的推陳出新，除了整體產品輕、薄、短、小等基 本需求外，通常在高功能、高傳輸、高效率等條件操作下，各種晶片、元件（例如CPU等）皆需在正常操作溫度下，方可發揮其效能，然而元件在操作時會產生 熱，如不將廢熱移除，會使得元件溫度提高，效率降低進而損傷元件，因此整體產品或元件之散熱功率需求將愈來愈高。

將廢熱藉由熱傳導方式，從元件傳至散熱片(Heat Sink)， 再經由熱對流或熱輻射方式使熱散失，此方法可有效地降低元件溫度，然而，在熱經由電子元件表面傳導至散熱片時，電子元件及散熱片表面均非平 坦、光滑，使兩者間無法完全貼合而產生縫隙，空氣為熱的不良導體，介面間產生縫隙時會使熱傳效率大幅降低，因此需要熱介面材料來填補縫隙，以增進熱傳效 率。

熱介面材料廣義的定義為介於發熱源與散熱器材的中間介質，除了一般常見的介於晶片與散熱鰭片間的 TIM(Thermal Interface Materials)或PCM(Phase Change Materials)，還包含LED散熱基板的MCPCB(Metal Core PCB)中的介電絕緣導熱層。在電子產品之散熱途徑中，熱介面材料為散熱功率高低之關鍵材料。

熱介面材料發展現狀
一般高分子材料之熱傳導值皆落在0.2 W/mK左右，因此要提升材料的熱傳導值便需加入高導熱的陶瓷粉體、奈米碳管、奈米石墨片(Graphene)等。

使用奈米碳管做為高導熱粉體添加於樹脂中，始終未能得到令人滿意的熱傳導值提升效果，推究其因，第一為碳管的長徑比 (Aspect Ratio)不足，第二為碳管在表面處理或分散過程中，碳管缺陷增多，導致本身熱傳導值下降，但大部分原因在於碳管與樹脂間相容性差，兩者間介面熱阻過 大，聲子在傳熱時易被散射，整體材料熱傳導特性無法提升。美國Georgia Institute of Technology 便將CNT做表面處理，降低粉體與樹脂間介面熱阻，以提升熱介面材料之熱傳導值，主要先將多層的奈米碳管(MWCNT)經由微波(Microwave)或 紫外線及臭氧(UV/Ozone)方式處理，再與環氧樹脂(Epoxy)做成複合材料。

圖二、CNT-polymer組成物的製備過程，使用雙面PI膠帶做為轉移層

為了使奈米碳管與樹脂的介面相容性更好，而使用了微波(Microwave)或紫外線/臭氧(UV/Ozone)的 方式來處理碳管，其處理結果可先從水滴的接觸角(Contact Angles of Water Droplets)測試得知（表一），未處理前的奈米碳管水滴接觸角為156°，經由微波處理後水滴接觸角為72°， UV/Ozone處理過後則是無法測到水滴接觸角，此結果指出UV/Ozone比微波處理能更有效將碳管表面官能基化(Carboxyl or Hydroxyl Groups)。

在表二中整理了不同處理方法的熱導係數，其測量方法為非接觸式的雷射閃光法(Contact-free Laser Flash Method, LFA 447)。由此可知，經由微波處理後，碳管複合材料有較高的熱導係數(2.6 W/mK)，其主因是微波處理可純化碳管，且將部分碳管表面官能基化而使其與樹脂有較好的相容性；雖然經由UV/Ozone處理過的碳管有更多的官能基， 但也破壞了碳管的大部分表面而缺陷增多，使CNT本身熱傳導值大幅降低。

在一個熱介面材料中，熱導值除了決定於所填充之粒子與基材本身之熱導值，也決定填充粒子在基材中所占的體積比；除此之外，填充粒子的粒徑分布與在基材中的分散情形，對材料整體之熱導值也扮演著重要的角色。
而粒子在基材中的分布情形，假設當不同大小的顆粒自由落下時，每個粒子可到達離底部的最低位子（圖八），粉體粒徑對熱導值之影響如圖九所示。

在粒子體積分率為40%、45%、50%時，粒徑分布越大，所得到的熱導值也越高，但是在體積比為55%時， 卻不是 粒徑分布最大的有著最高的熱導值，這是因為一開始在粒徑分布增大時，粒子間的碰觸機會增加而增多了熱傳通路，因而熱傳時的阻值隨之降低，進而提高熱導值； 相對地，粒徑分布的增加，也伴隨著熱傳粉體之可接觸面積減少，以及在材料表面粒子填充數目的減少，這些不利因素使得在體積比為55% 時，熱導值並不會隨著粒徑分布的增大而增大。

圖九、粉體填充體積分率為50%時，粒徑分布對於熱傳導值的影響

熱介面材料市場趨勢
由於矽氧烷類較一般有機樹脂有較好的耐溫性及抗化性，而導熱粉體仍是以氧化鋁成本最低，所以目前市場上構成熱介面材料主要還是以矽氧烷類及氧化鋁為大宗。

市面上熱介面材料大致可分為有一定形狀之固體狀（如Pad）、無定形液體狀（如Grease）兩類，固體狀主要應用 於如LCD TV民生用品上，價格是最主要競爭方向，材料本身之熱傳導值、低硬度、耐燃性或絕緣性等機能，也是主要之附加價值；液體狀熱介面材料則朝可薄膜塗佈化、低 黏度化及不油膩沾黏等特性發展。目前市場動向、需求發展如表七至表九所示……以上內容為重點摘錄，如欲詳細全文請見原文

帝 人化成跨入高熱傳導性PC樹脂的市場，研發出業界最高熱傳導率等級的PC樹脂。新技術係搭配特殊的石墨，除了可兼顧PC樹脂原本的剛性及強度以外，熱傳導 性也比以往的產品提高至10～100倍，該公司的產品項目除了一般性的PC樹脂以外，尚有難燃性PC樹脂的產品項目。目前以LED照明及OA機器為主，展 開推廣販售，期望可在3年後達到10億日幣的營業規模。 

近年PC及智慧型手機等可攜式機器對於高機能及小型化的需求，由中央運算裝置（CPU）等熱源的所發散的熱量大幅增 加。另外，隨著LED照明、屋外廣告看板、液晶電視等光源的正式普及採用，散熱對策遂成為製造商產品研發時最重要的課題。舊有樹脂產品的弱點為散熱性不 佳，該款高熱傳導性樹脂可大幅提高樹脂產品的散熱性能，可擴大應用至對於散熱特性有高度需求的照明、電子、汽車、OA機器等領域。

該公司採用特殊的石墨為填料，研發出三種一般型的產品，再加搭配特殊石墨及難燃劑，可兼具熱傳導性及難燃性的難燃性 產品項目共三種，合計六款產品。使用獨家搭配技術，將特殊石墨呈均一分散，可同時維持與以往產品相同的機械特性，還可實現高熱傳導率。通常PC樹脂的熱傳 導率為0.1～0.2W/m.K，帝人化成所研發出的一般類型產品熱傳導率為4～11W/m.K，難燃類型為1～4 W/m.K，難燃類型產品還通過美國安全檢查規格（UL）94的V-O（1.8mm）。

該公司產品的優勢除了高熱傳導特性以外，相較於多用於散熱材料的Aluminum die casting等金屬材料，其優點為可提高機器的輕量化及高設計自由度。已應用於螢光燈、Down Light、散熱風扇、Lamp Holder等LED相關照明的部分用途，目前已展開客戶端的樣品出貨，期望可早日達到實用化的目標。
