Grinding Polishing Sandblasting Refractory Materials Black Silicon Carbide - China

price: contact company for price

Black silicon carbide is produced in a high temperature electric resistance-

type furnace from a mixture of quartz sand and petroleum coke. The

hardness of black silicon carbide is greater than fused alumina but less

than synthetic diamond. Its mechancial intensity is greater than fused

alumina, but is brittle and very sharp. The mineral has some electrical

and heat conductivity.
