Introduction of Green Silicon Carbide

Silicon carbide (SiC) is made of quartz sand, petroleum coke (or coal coke), sawdust, and salt as additives through high temperature smelting of resistance furnace. Among diamonds, the mechanical strength is higher than that of corundum. It has stable chemical properties, high thermal conductivity, small thermal expansion coefficient, and good wear resistance. In addition to being used as abrasive, it has high temperature resistance and thermal conductivity, making it one of the preferred kiln furniture materials for tunnel kilns or shuttle kilns.
