How much do you know about silicon carbide?

Silicon carbide is made of quartz sand, petroleum coke, and silica as raw materials, and is smelted at high temperature in an electric furnace. It has the advantages of high hardness, 

stable chemical properties, high

thermal conductivity, low thermal expansion coefficient, and good wear resistance. So what are the characteristics of silicon carbide?

Characteristics of silicon carbide:

1. Silicon carbide powder is coated on the inner wall of the turbine impeller or cylinder body by a special process, which can improve its wear resistance and extend its service life by 1 to 2 times;

2. The refractory material made of it is resistant to thermal shock, small in size, light in weight, high in strength, and has good energy-saving effect.

3. Low-grade silicon carbide is an excellent deoxidizer. It can speed up steelmaking, facilitate control of chemical composition, and improve the quality of steel.

4. Silicon carbide has a high hardness, with a Mohs hardness of 9.5, second only to diamond. It has excellent thermal conductivity and is a semiconductor that can resist oxidation at high temperatures.

5. Silicon carbide is an abrasive containing more than 99% silicon carbide. Its hardness is between corundum and diamond, and its mechanical strength is higher than corundum, so it is mainly used to 

grind carbide tools.

6. Silicon carbide has good self-sharpening properties and is mostly used to process carbide, titanium alloy and optical glass. It is also used to hone cylinder liners and finely grind high-speed steel tools.
