Silicon carbide

Silicon carbide is – after diamond and boron carbide – the third-hardest mineral in the world. Chemically, silicon carbide is extremely resistant and able to withstand the strongest alkalis and acids. In addition to being used as a blasting medium and abrasive, silicon carbide is also used as an aggregate for the production of non-slip, wear-resistant and conductive floor coatings. We will be happy to help you…
