Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C (4,700° F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°–1,600° C (2,550°–2,900° F). For fabriion, a process developed in the 1920s is employed: the powdered tungsten carbide is mixed with another

Silicon Carbide SiC Material Properties
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.
