DESCRIPTION
Black silicon carbide (SIC), also known as silicon carbide, is made from quartz sand and carbon (anthracite tar or petroleum coke) at high temperature in an electric furnace. It has the characteristics of high hardness, good thermal conductivity, good electrical and thermal conductivity, small thermal expansion, high wear resistance. Therefore, SIC is the most suitable material for abrasives, refractory materials, metallurgical deoxidizers, special ceramics, electric heating elements, etc.
