Factory Supply Green/Black Silicon Carbide for Refractory Introduction of the silicon carbide: Silicon carbide is made of quartz sand, stone tar (or coal), wood chips and other raw materials in the resistance by high temperature smelting, silicon and carbon bonds made of ceramic compounds.
This Green Silicon Carbide is made by using quartz sand and petroleum coke and sodium chloride as basic materials at temperatures above 1800℃. It has high hardness, good thermal conductivity, low coefficient of thermal expansion, stable chemical properties, good wear resistance and brittleness. Its hardness is between fused alumina and diamond.
Properties of Silicon Carbide SiC is a ceramic material with an outstanding hardness, only surpassed by diamond, cubic boron nitride and boron carbide. The material is highly wear resistant and chemically inert to all alkalies and acids. It is also highly heat resistant.
