Black silicon carbide Introduction

Silicon carbide is divided into black and green silicon carbide. Silicon carbide, also known as Moissanite. In contemporary C, N, B and other non-oxide refractory materials in high-tech, silicon White fused aluminum oxide carbide is the most widely used and most economical one. Can be called emery or refractory sand. Where: Black silicon carbide is quartz sand, petroleum coke and quality silica as the main raw material, smelting electric arc furnace. Its hardness between corundum and diamond, corundum higher mechanical strength, brittle and sharp. Silicon carbide, metallic luster, containing more than SiC 95%, greater than the intensity of green silicon carbide, but lower hardness, is mainly used for grinding cast iron and non-metallic materials
