ELECTRICAL PROPERTIES OF GROUP V CARBIDES

Like the other interstitial carbides, the Group V carbides are electrical conductors (see Ch. 4, Sec. 3.1). Their electrical properties are shown in Table 5.5.[5iratio] 

Compound Electrical Resistivity at 20°C (pQ-cm) Hall Constant at 20°C 10 cm /A S Magnetic Susceptibility 10 emu/mol 

The electrical resistivity of the carbides is only slightly higher than that of the host metals, reflecting the metallic character of these compounds and their strong metal-to-metal bond. The nitrides and especially the borides have lower resistivity. The Hall constant is negative, like that of the Group IV carbides (see Sec. 3.2 of Ch. 4).
