Black Silicon Carbide
Informação de produto geral
BlackSilicon Carbide is produceed at high temperature in an electric resistance type furnace with puarts sand and petoleum coke as its main raw * hardness is between fused aluina and synthetic diamond mechanical intensity of it is higher than fused alumina.It is brittle and sharp and has electrical and heat conductivity in some degree.The abrasives made of it are suitable for working on cast iron,nonferrous metal,rock leather,rubber,etc..It is also broadly used as refractory material and metallurgical additive.
