The classification of refractory compounds, the basic models of the condensed state of matter, which are the theoretical basis for understanding the formation of the properties of materials based on refractory compounds, and the concept of the “introduction phase”, which includes a large number of refractory compounds, are considered. The main types of crystal lattices formed in the structures of the most common refractory compounds of transition metals with light nonmetals (carbon, nitrogen, boron and silicon) and mutual compounds of these nonmetals are considered. The peculiarities of their electronic structure and its influence on the basic properties of refractory compounds are analysed in terms of the provisions of the configuration model of matter.

For students of materials science, metallurgy, and mechanical engineering specialities of higher technical educational institutions. It may be useful for postgraduate students, researchers and engineering and technical workers.
