Vanandium Carbide(VC) , is an acutely harder adverse bowl actual (9-9.5 Mohs, possibly the hardest metal-carbide known). It is commercially acclimated in apparatus $.25 acid tools. It has the actualization of gray brownish crumb with cubic clear structure.
Vanadium carbide is chemically abiding and has accomplished high-temperature property. It can be acclimated as an accretion to tungsten carbide to accomplished the carbide crystals to advance the acreage of the cermet. Vanadium carbide can be formed in the (111) orientation, if formed by radio abundance magnetron sputtering. Although vanadium carbide is a actual thermodynamically abiding ceramic, V2C is activity favorable to abide at temperatures aloft 900°C.
