The II-VI wide-band compounds zinc sulfide, cadmium sulfide and Cd[sub x]ZN[sub 1[minus]x]S ternary alloys has been of considerable technological interest due to their semiconducting, optical and mechanical properties and are of considerable importance as photoconductors, phosphors, infrared and solar-cell window materials and materials for short-wavelength optoelectronic applications. Structures and phase relation in the ZnS-CdS system were investigated in the temperature range 150-700 C and the boundaries describing the equilibria between the zinc-blend and wurtzite Cd[sub x]An[sub 1[minus]x]S solid solutions were determined by examining the ion exchange processes Cd[sup 2+] [r arrow] Zn[sup 2+] in the ZnS powder. The complete thermodynamical description of the ZnS-CdS system is proposed. It was found, that Cd[sub x]Z[sub n[minus]1]S solid solutions of both modifications obey a regular solution model. Enthalpies of the zinc-blend-to-wurtzite structural phase transition in CdS (550[plus minus]50 J/mol) and in ZnS (1700[plus minus]100 J/mol) were defined. The solid state phase diagram calculated from defined thermodynamical parameters agrees well with the experimental data.
