The selection first offers information on continuous-discrete character of variation of the type of bonding in refractory compounds of transition metals, principles of classification of refractory compounds, and calculation of the energy of crystal lattices of inorganic compounds.
The text also takes a look at the X-ray spectral investigation of chemical bonding forces in hydrides of refractory metals, using titanium and vanadium compounds as examples and comparison of X-ray K absorption spectra in compounds of chromium with elements of subgroup IV.
The manuscript elaborates on the X-ray spectra and interatomic bond in solid metallic compounds and behavior of components of metal solid solutions in a field of electrical forces. The publication also examines the electrical properties of hexaborides of several rare earth metals and the thermionic emission properties of scandium gadolinium borides.
The book is a dependable reference for readers wanting to study refractory compounds.
