grinding / polishing / blasting material black silicon carbide
1. Application of silicon carbide
- With the content of more than 95% SiC, the toughness of black silicon carbide powder is higher than that of green silicon carbide.
- It is mostly used to process materials with low tensile strength, such as glass, ceramics, refractories, stone, cast iron and non-ferrous metals.
2.Product Introduction of black silicon carbide
- To get black silicon carbide powder,the mixed powder is made of carbon powder and black silicon powder according to the molar ratio of 1:1.
- The grinding ball and powder are sealed in argon tank at the mass ratio of 40:1, and the mechanical ball milling is carried out on the ball mill.
- After 25 hours, the black silicon carbide powder with an average grain size of about 6nm was obtained.
