Vanadium nitride is a black semi-metallic solid with a homogeneity area VN _1.0 -VN _0.7 and a crystal structure of the sodium chloride type. Vanadium nitride, vanadium carbide and vanadium (II) oxide have isotypic crystal structures in which nitrogen, carbon and oxygen can be exchanged and form mixed crystals. Vanadium nitride forms solid solutions with titanium nitride , niobium nitride , titanium carbide , niobium carbide and tantalum carbide .
