碳化硅用途?

?

? ? ? 1、磨料切割工具：由于碳化硅的耐用性和低成本，在現代寶石加工中作為常用磨料使用。碳化硅憑借其硬度使它在制造業中諸如砂輪切割、搪磨、水刀切割和噴砂等磨削加工過程中，將碳化硅粒子層壓在紙上就能制成砂紙和滑板的握帶。還可用于用于制作砂輪、砂紙、砂帶、油石、磨塊、磨頭、研磨膏等。

? ? ? 2、結構材料：碳化硅材料可用于制造復合裝甲和背心中的陶瓷板。

? ? ? 3、天文學：碳化硅具備的低熱膨脹系數、高的硬度、剛性和熱導率使其能夠作為天文望遠鏡的鏡面材料。通過化學氣相沉積制造的直徑達3.5米和2.7米的多晶碳化硅圓盤已被分別安裝在赫歇爾空間天文臺和同溫層紅外線天文臺等幾個大型天文望遠鏡上。

? ? ? 4、催化劑載體：碳化硅本身的抗氧化性質和立方β-SiC所具有的大比表面積使其可作為非均相催化劑的載體。通過稻殼炭化合成的β-SiC已被用于作為非均相催化劑的載體應用于催化諸如正丁烷氧化生成這類烴類的氧化反應。

? ? ? 5、磨料磨具: 主要用于制作砂輪、砂紙、砂帶、油石、磨塊、磨頭、研磨膏及光伏產品中單晶硅、多晶硅和電子行業的壓電晶體等方面的研磨、拋光等。

? ? ? 6、 化工：可用做煉鋼的脫氧劑和鑄鐵組織的改良劑，可用做制造四氯化硅的原料，是硅樹脂工業的主要原料。碳化硅脫氧劑是一種新型的強復合脫氧劑，取代了傳統的硅粉碳粉進行脫氧，和原工藝相比各項理化性能更加穩定，脫氧效果好，使脫氧時間縮短，節約能源，提高煉鋼效率，提高鋼的質量，降低原輔材料消耗，減少環境污染，**勞動條件，提高電爐的綜合經濟效益都具有重要價值。

? ? ? 7、節能：利用良好的導熱和熱穩定性，作熱交換器，燃耗減少20，節約燃料35，使生產率提高20-30，特別是礦山選廠用排放輸送管道的內放，其耐磨程度是普通耐磨材料的6--7倍。

? ? ? 8、耐材：利用碳化硅具有耐腐蝕、耐高溫、強度大、導熱性能良好、抗沖擊等特性，碳化硅一方面可用于各種冶煉爐襯、高溫爐窯構件、碳化硅板、襯板、支撐件、匣缽、碳化硅坩堝等。另一方面可用于有色金屬冶煉工業的高溫間接加熱材料，如豎罐蒸餾爐、精餾爐塔盤、鋁電解槽、銅熔化爐內襯、鋅粉爐用弧型板、熱電偶保護管等；用于制作耐磨、耐蝕、耐高溫等高級碳化硅陶瓷材料。

Silicon carbide profile
Silicon carbide is using quartz sand and petroleum coke , wood chips as raw material through high temperature resistance furnace smelting and. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide is also called moissanite. In the contemporary C, N, B and other non oxide high technology refractory raw materials, silicon carbide is the most widely used and most economical one. Steel sand or refractory sand can be called. Silicon carbide is with quartz sand and petroleum coke , wood and other raw materials in the resistance furnace high temperature smelting and become classics. At present, Chinas industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two kinds, are six square crystal, the proportion is 3.20 3.25, the micro hardness is 2840 3320kg/mm2.
Silicon carbide characteristics
Silicon carbide has stable chemical properties, high thermal conductivity, low thermal expansion coefficient, good wear resistance, corrosion resistance, high temperature resistance, high strength, good thermal conductivity, impact resistance and other characteristics. Silicon carbide made of high-grade refractory materials, heat shock, small size, light weight and high strength, energy saving effect is good.
Silicon carbide applications
1, abrasive cutting tools: due to the durability of silicon carbide and low cost, in the modern gem processing as a commonly used abrasive. Silicon carbide with its hardness make it in manufacturing industry, such as grinding wheel cutting, honing, water jet cutting and sandblasting etc. in the grinding process, lamination of SiC particles in the paper can be made of sandpaper and skateboard grip strips. Can also be used for the production of sandpaper, abrasive, grinding wheel, oilstone, grinding, grinding head, grinding paste etc
