(1)Silicon carbide,Commonly known as emery.Use quartz sand and petroleum coke (or coke), sawdust as raw material through high temperature resistance furnace smelting and become.
(2)In the contemporary C, N, B cells and other high technology not oxide refractory raw material, silicon carbide is the most widely used and the most economic one.
(3)At present our country industrial production of silicon carbide is divided into Black Silicon Carbide and Green Silicon Carbide two kinds, all is the six-party crystal, specific gravity of 3.20 ~ 3.25, microhardness for 2840-3320 kg/mm2.
(4) Featured by high hardness, small coefficient of expansion, brittle property and good thermal conductivity.
Black silicon carbide is quartz sand, petroleum coke in primary raw materials, smelting in the high temperature resistance furnace. Its hardness is between corundum and diamond; the mechanical strength is higher than fused alumina, brittle and sharp. It has a certain conductivity and thermal conductivity. HS Code 28492000, CAS No. 409-21-2.
