Silicon carbide (SiC) is used quartz sand, petroleum
coke (or coal), wood chips as raw material through high temperature resistance
furnace smelting made.Silicon carbide is also called moissanite. Silicon
carbide is most widely used in the modern C, N, B, and other non oxide high
technical refractory raw materials.Silicon carbide hardness is very high, Black silicon carbide containing SiC about 95%, its
toughness is higher than green silicon carbide, most of the material used for
processing low tensile strength of materials, such as glass, ceramics, stone,
refractory, cast iron and non-ferrous metals, etc.
