Silicon carbide (SiC) is made of quartz sand, petroleum coke (or coal coke), and wood chips (salt needs to be added to produce green silicon carbide) through high temperature resistance furnaces. Silicon carbide also exists in nature as a rare mineral, moissanite. Silicon Carbide is also called Carborite.
Quartz sand, coal coke (petroleum coke), and sodium chloride are smelted at high temperature in a resistance furnace.
Silicon carbide is mainly used for the grinding and polishing of abrasive wheels, sandpaper, abrasive belts, whetstones, grinding blocks, grinding heads, grinding pastes, and single crystal silicon in polycrystalline silicon, polycrystalline silicon, and piezoelectric crystals in the electronics industry.
as abrasive material.such as grinding wheel, whetstone, grinding head, sand tile, etc.
as a metallurgical deoxidizer and high temperature resistant material.
single crystals of high purity, can be used in the manufacture of semiconductor, the manufacture of silicon carbide fibers.
Silicon carbide has stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance.
