The electrical properties of chromium borides,carbides, and nitrides

Summary The electrical properties of borides, carbides and nitrides of chromium were studied, which made it possible to elucidate certain questions of the electron structure of the given phases.It was established that for an atomic proportion of metalloid of 0.25 there is a quantitive correlation between the electrical resistance and the magnitude of its first ionization potential.The variation in the electrical properties with a rise in the metalloid content in the systems Cr-B, Cr-C and Cr-N is explained by the differences in the effects of atoms of boron, carbon and nitrogen on the value of the overlapping of 4s and 4p chromium bands, on the degree of its d-state defect, and also the difference in the ionization potentials of the indicated metalloids.
