These include non-ferrous metal grinding (copper or aluminum alloys); cermets of ceramic (cemented tungsten-carbide, metal matrix composite Al-Si-C); and glass, silicon, granite, or marble. While the crystal structure of diamond and CBN is very similar, there is one difference: the carbon atoms of the diamond crystal structure have four valence electrons.
Tungsten Carbide Powder Coating materials are always often available in powder or wire form and made from metal, plastics alloys or composites. These substances are then heated by an electrical arc, plasma or by mechanical means to a molten state and are then discharged onto a surface.
tungsten carbide used for grinding silica powder

Material of the month – silicon carbide | IOM3
Sitting at an impressive 9–9.5 on the Mohs hardness scale, silicon carbide proved to be a much more powerful abrasive than those based on emery, corundum and garnet that came before. Alongside synthetic alumina, silicon carbide abrasives reigned supreme until 1955, when Howard Tracy Hall at the General Electric Company (GE) finally succeeded in producing synthetic diamonds.
