Silicon Carbide has a lower hardness and abrasive capacity than industrial diamond and boron carbide. Yet because of its much lower cost when compared with diamond or B4C, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts. It is therefore perfect for sandblasting ...

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.
