Silicon Carbide (SiC) Properties and Appliions

Ultra fine silicon-carbide produced in electric arc is used as insulation in cryogenic appliions. Its low neutron cross-section and good resistant to radiation damage make it useful in nuclear reactor appliions. Other uses of fine silicon carbide powder include preparation of mould coating for batch casting of molten metals.

Microsilica - Carbon

Microsilica is the by-product of an unrelated industry, the production of ferroalloys. The raw materials for the production of ferrosilicon, silicon metal and Microsilica are quartz and reducing agents, mainly coal and coke. The overall reaction in the furnace is: SiO 2 (from quartz) + 2C (from coal/coke) = Si and 2CO.
