Black Silicon Carbide

Short Description:

FEATURES Silicon carbide is made from quartz sand, petroleum coke (or char), sawdust from electric arc furnace smelting. In nature there are also rare silicon carbide mineral moissanite. Silicon carbide, also known as Moissanite. In contemporary C, N, B and other non-oxide refractory materials in high-tech, silicon carbide is the most widely used and most economical one. Can be called emery or refractory sand. Silicon carbide is with quartz sand, petroleum coke (or coal tar), wood (green sil...

    FEATURES

    Silicon carbide is made from quartz sand, petroleum coke (or char), sawdust from electric arc furnace smelting. In nature there are also rare silicon carbide mineral moissanite. Silicon carbide, also known as Moissanite. In contemporary C, N, B and other non-oxide refractory materials in high-tech, silicon carbide is the most widely used and most economical one. Can be called emery or refractory sand. Silicon carbide is with quartz sand, petroleum coke (or coal tar), wood (green silicon carbide need to increase the production of salt) and other raw materials in high temperature resistance furnace smelting. At present China’s industrial production of silicon carbide is divided into two kinds of black silicon carbide and green silicon carbide, are hexagonal crystals, accounting for 3.20 to 3.25, microhardness 2840 ~ 3320kg/mm2

    Grit size :12#-220#;
    Micropowder: 240#-1200#.

    Character
    SIC 88%-97%,
