       碳化硅主要分为黑碳化硅和绿碳化硅。碳化硅又称碳硅石，在当代C、N、B等非氧化物高技术耐火原料中，碳化硅为应用广泛、经济的一种，可以称为金钢砂或耐火砂；其中黑碳化硅是以石英砂,石油焦和优质硅石为主要原料,通过电阻炉高温冶炼而成，其硬度介于刚玉和金刚石之间，机械强度高于刚玉,性脆而锋利。

       黑碳化硅含SiC约98，有金属光泽，其韧性高于绿碳化硅，大多用于加工抗张强度低的材料，如玻璃、陶瓷、石材、耐火材料、铸铁和有色金属等，主要用于磨铸铁和非金属材料。绿碳化硅含SiC约98.5以上，自锐性好，大多用于加工硬质合金、钛合金和光学玻璃，也用于珩磨汽缸套和精磨高速钢刀具。此外还有立方碳化硅，它是以特殊工艺制取的黄绿色晶体，用以制作的磨具适于轴承的超精加工，可使表面粗糙度从Ra320.16微米一次加工到Ra0.040.02微米。

       1、碳化硅颗粒可以增加石墨形核核心，增强石墨形核能力。降低铁水的过冷度、降低铸件白口倾向。

       2、良好的脱氧效果，净化铁水。延长炉衬使用寿命。

       3、减少灰铸铁中的过冷石墨，促使A型石墨的生成。

       4、在球铁生产中加入可增加石墨球数、提高球化率，使石墨球更加圆整细小，并可减少球化剂的加入量。

       1、磨料；碳化硅具有很高的硬度，化学稳定性和一定的韧性,所以碳化硅能用于制造固结磨具、涂附磨具和自由研磨，从而来加工玻璃、陶瓷、石材、铸铁及某些非铁金属、硬质合金、钛合金、高速钢刀具和砂轮等。

       2、耐火材料和耐腐蚀材料；主要是因为碳化硅具有高熔点(分解度)、化学惰性和抗热振性,所以碳化硅能用于磨具、陶瓷制品烧成窑炉中用的棚板和匣钵、炼锌工业竖缸蒸馏炉用的碳化硅砖、铝电解槽衬、坩锅、小件炉材等多种碳化硅陶瓷制品。

       3、化工用途；因为碳化硅可在溶融钢水中分解并和钢水中的离氧、金属氧化物反应生成和含硅炉渣。所以它可作为冶炼钢铁的净化剂,即用作炼钢的脱氧剂和铸铁组织改良剂。这一般使用低纯度的碳化硅,以降低成本。同时还可以作为制造四氯化硅的原料。

       4、电工用途；用作加热元件、非线性电阻元件和高半导体材料。加热元件如硅碳棒(适用于11001500工作的各种电炉),非线性电阻元件,各式的避雷阀片。

       5、配制远红外 涂料或制成碳化硅硅板用远红外 干燥器中。

       6、碳化硅捣打料以碳化硅为材料(SiC含量98.5)，以磷酸二氢铝作为结合剂，并添加其它材料精心配制而成。其主要特点是：强度高，抗液态渣侵蚀能力强，能是较稀液态渣在旋风筒壁上形成一层薄膜，起到保护内衬的作用。该材料导热性好，热膨胀系数小，抗氧化能力强，热震稳定性能 ，主要用在旋风筒内壁及垃圾焚烧炉等工业窑炉。

       7、碳化硅微粉主要用于耐火材料类产品的制造、泡沫陶瓷行业、太阳能硅板切割、水晶切割研磨、汽车发动机原件制造、特种涂料行业、塑料制品改性、脱硫、供电、环保行业等。功能陶瓷、高级耐火材料、磨料及冶金原料。

Introduction of silicon carbide

Green silicon carbide mainly divides into the black silicon carbide and silicon carbide. Silicon carbide is also called the moissanite. In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic. Can be called corundum sand or refractory. Among them: black silicon carbide is quartz sand and petroleum coke and high quality silica as the main raw material, through high temperature electric resistance furnace smelting. Its hardness is between fused alumina and between diamond and mechanical strength higher than that of corundum, sharp and crisp.

Silicon carbide purpose

1, abrasive; Silicon carbide with high hardness, chemical stability and certain toughness, so sic grinding tool can be used in the manufacture of consolidation, coated abrasive grinding and freedom, to the processing of glass, ceramic, stone, cast iron and some non-ferrous metals, hard alloy, titanium alloy, high speed steel cutting tools and grinding wheel etc.

2, refractory materials and corrosion resistant material; Mainly because of silicon carbide with high melting point (decomposition), chemical inertness and reting resistance, so the silicon carbide can be used for abrasive, ceramic firing kiln shed board, sagger and used in the zinc smelting industry vertical distillation furnace with silica brick, aluminum carbide cylinder electrolytic cell line, crucible, small furnace material of silicon carbide ceramics and other products.

3, chemical purposes; Because of the silicon carbide can be decomposed in the liquid steel melt and molten steel from oxygen, metal oxide reaction of carbon monoxide and slag containing silicon. So it can be used as a purifying agent of smelting steel and used for steelmaking deoxidizer and cast iron modifier. This generally using low purity of silicon carbide, in order to reduce the cost. At the same time also serve as raw materials for the manufacture of silicon tetrachloride.

4, electrical purposes; Used as a heating element, high nonlinear resistance element and semiconductor materials. Heating elements such as silicon carbide (applicable to 1100 1500 work of various electric furnace), nonlinear resistance element, all kinds of lightning protection of valve plate.

5, other mixture far-infrared radiation coating made of silicon carbide silicon or with far infrared radiation in the dryer.

6, the ramming material with carborundum (SiC content of 98.5 or higher) for material, with aluminum dihydrogen phosphate as binder, and add made from other materials carefully. Its main features are: high strength, liquid slag erosion resistance is strong, can be a thin liquid slag in a layer of thin film is formed on a whirlwind wall, have the effect of lining protection. The material thermal conductivity is good, small thermal expansion coefficient, oxidation resistance is strong, good thermal shock stability, mainly USES in the cyclone tube wall and garbage incinerator and other industrial kiln.

7, silicon carbide powder is mainly used for refractory products manufacturing, and foam ceramic industry, solar silicon original cutting, crystal cutting, grinding, car engine manufacturing, special coating industry, plastics modification, desulfurization, power supply, environmental protection industry, etc. Functional ceramics, refractories, abrasives and metallurgical raw materials.
