  • 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.
