iC, also known as carbon化硅 (carborundum), silicon carbide, is a wear-resistant material produced by high-temperature smelting in a resistance furnace using raw materials such as quartz sand, petroleum coke (or coal coke), and wood shavings. It is insoluble in acids at room temperature but soluble in alkalis and exhibits semiconductor properties. The melting point of silicon carbide is 1420°C. It is widely used in metallurgy, chemical industry, casting, semiconductor materials, and refractory materials. Industrial silicon production can be divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals with a specific gravity of 3.20-3.25, SiO2 content of 97-98%, Mohs hardness of 9.5, and

Fe2O3 content of 0.02%. Black silicon carbide, containing about 98% SiC, has a metallic luster and higher toughness than green silicon carbide. It is mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron, and non-ferrous metals. It is primarily used for grinding cast iron and non-metallic materials. Green silicon carbide, containing more than 98.5% SiC, has good self-sharpening properties and is mostly used for processing hard alloys, titanium alloys, and optical glass. It is also used for honing cylinder blocks and precision grinding of high-speed steel tools. In addition, there is cubic silicon carbide, which is a yellow-green crystal obtained by a special process. The abrasive tools made from it are suitable for the super-precision processing of bearings, which can achieve a surface roughness from Ra32-0.16 micrometers to Ra0.04-0.02 micrometers in one pass. silicon carbide.
