Silicon Carbide (SiC) is produced by quartz sand, petroleum coke or anthracite and sawdust through electric resistance furnace under the high temperature. It is black opaque body hexagonal crystal with Moh's hardness up to 9.15-9.5, which is ranked second in the hardness just after the diamond.
Silicon Carbide (SiC) is featured with below advantages
1. Stable chemical performance
2. Great Hardness and Strength
3. Great corrosion resistance and wear resistance
4. Good heat conductivity
5. Low heat expansion coefficient
SiC Carbide (SiC) application
1. Lapping and polishing medium
2. Grinding wheels, grinding paper and other grinding medium
3. Pressure blasting
4. Jetting blasting
5. Grinding, polishing, lapping, sandblasting
6. Steel industry
A. Remove oxygen during steel manufacturing process
B. Adjust carbon content
C. To be catalyzer to improve steel quality
7. Lining of furnace to improve age
8. Building materials to improve skidding and wear resistance and using age, including high way and airport
9. Producing semi-conductor, SiC fabrics
10. Widely application in ceramics industry
