Silicon Carbide Powder
Description:
Silicon Carbide brittle and sharp has electrical and heat
conductivity in some degree.The abrasives made of it are suitable
for working on cast iron,non-ferrous metal,rock,
leather,rubber,etc.It is also broadly used as refractory material
and metallurgical additive.

Application:
Silicon Carbide is an inorganic substance with the chemical formula SiC. It is
smelted at high temperature in a resistance furnace using raw
materials such as quartz sand, petroleum coke (or coal coke), and
wood chips (salt is required when producing green silicon carbide).
Silicon carbide also exists in nature as a rare mineral,
moissanite. Among non-oxide high-tech refractory raw materials such
as C, N, and B, silicon carbide is the most widely used and
economical one, and can be called emery sand or refractory sand.
Silicon
Carbide has two commonly used basic varieties: black silicon carbide and
green silicon carbide.
Green silicon carbide
powder has stable chemical properties, high thermal conductivity, small
thermal expansion coefficient, and good wear resistance. In
addition to being used as an abrasive, silicon carbide has many
other uses. For example, silicon carbide powder is coated on
turbine impellers or cylinder blocks using special processes. The
inner wall can improve its wear resistance and extend the service
life by 1 to 2 times; the advanced refractory material made of it
is thermal shock resistant, small in size, light in weight, high in
strength, and has good energy saving effect.
Black Silicon Carbide
Powder is an excellent deoxidizer. It can speed up steelmaking,
facilitate control of chemical composition, and improve the quality
of steel. In addition, silicon carbide is also widely used in the
production of silicon carbide rods for electric heating elements.
