Product Description

Black Silicon Carbide Black silicon carbide (SIC) is made from quartz sand and carbon( anthracite coal tar or petroleum coke) in electric esistance furnace at high temperature. It has the characteristic of high hardness, excellent electrical and heat conductivity, low thermal expansion, and high abrasion resistance. Thus, SIC is the most suitable material of abrasives, refractories, deoxidizer of metallurgical, special ceramics, electric heating elements and so on.
