Where is it used?
Silicon carbide - after diamond and boron carbide - is the third hardest mineral in the world. Chemically, silicon carbide is extremely resistant and can withstand the strongest alkalis and acids. Silicon carbide is used as a blasting medium and abrasive, as well as an aggregate in the manufacture of non-slip, wear-resistant and conductive floor coverings.
Scope of Applications
