Theoretical models of ordered alloys of quaternary systems based on Bi-Sb-Se-Te have been developed. A scheme of distribution of phase regions of quaternary systems based on ternary systems has been constructed using phase diagrams of binary alloys of the initial components Bi-Te, Bi-Sb, Bi-Se, Te-Sb, Sb-Se, Te-Se. Isothermal cross-sections of quaternary systems at different temperatures are presented, on the basis of which conoid triangles are constructed and cases of congruent and incongruent melting are predicted for materials with programmable properties.
