DTA data were used to construct the liquidus isotherms at 400 and 500/sup 0/C in the region of InSb segregation from In--Sb--Te alloys. The pattern of location of the region of InSb-based solid solutions in the system In--Sb--Te is used to examine the stability of solid solutions based on binary diamond-like compounds in the systems A/sup III/--B/sup V/--C/sup VI/. Elongation of the solid solution region in these systems toward the A/sup III/--C/sup VI/ side is evidently a general rule and is due to the fact that in these solid solutions, as in other diamond-like phases, the empirical rule 4 el/atom is observed. For alloys of ternary solid solutions it may be written N/sub v/ = ((3x + 5y + 6z)/100) = 4 el/atom where N/sub v/ is the number of valence electrons per solid solution atom, and x, y, and z are, respectively, the concentrations of elements of subgroups IIIB, VB, and VIB in the solid solution in at. percent. Strict observance of the rule is characteristic of alloys lying in the cross sections A/sup III/B/sup V/--A/sub 2//sup III/C/sup VI/ and A/sup III/B/sup V/--A/sub 2//sup III/C/sub 3//sup VI/ (for example InSb--In/sub 2/Te and InSb--In/sub 2/Te/sub 3/). However, the rule is not strictly observed, but rather manifested as a tendency, because some of the valence electrons of the C/sup VI/ element at least are not involved in formation of the sp/sup 3/-hybrid bonds. Thus, in the system In--Sb--Te, the region of InSb-based solid solutions is somewhat displaced from the InSb--In/sub 2/Te cross section. An analysis of interaction in the corresponding system reveals that in the systems In--B/sup V/--Te and In--B/sup V/--Se the location of the region of solid solutions based on InB/sup V/ must be similar to that in the system In--Sb--Te.
