FAQs of Black And Green Silicon Carbide:

Q: How is black and green silicon carbide manufactured?

A: Black and green silicon carbide are produced by reacting high purity silica sand and petroleum coke in an electric resistance furnace at high temperatures. The process gives black silicon carbide a slightly lower purity, while green silicon carbide obtains even higher purity due to better chemical control during synthesis.

Q: What are the main differences between black and green silicon carbide?

A: Black silicon carbide typically has a purity of 98% minimum and Mohs hardness of 9.29.3, featuring slightly more impurities. Green silicon carbide, at 99% purity minimum and Mohs hardness of 9.49.5, is harder and contains fewer impurities, making it better suited for fine grinding and polishing applications.

Q: When should silicon carbide be used in industrial applications?

A: Silicon carbide is an excellent choice for challenging environments requiring high hardness, thermal conductivity, and resistance to wear. It is ideal for use in abrasive blasting, grinding wheels, refractory linings, polishing, and the manufacture of cutting tools.

Q: Where can black and green silicon carbide be sourced in India?

A: Black and green silicon carbide can be procured from authorized exporters, importers, and suppliers across India. It is widely available through industrial raw material distributors who cater to abrasive, refractory, metallurgy, and ceramics industries.

Q: What is the benefit of using silicon carbide in abrasive blasting and grinding?

A: Silicon carbides exceptional hardness and sharp-edged grains provide superior cutting efficiency and longer service life in abrasive blasting and grinding applications, resulting in smoother surfaces and more precise finishes.

Q: How does grain size customization improve application performance?

A: Custom grain sizes enable manufacturers to match the silicon carbide to the precise requirements of their process, optimizing material removal rates, surface finish quality, and overall operational efficiency.
