The authors study the nature of the dissolution of thallium in ternary phases. They have synthesized alloys of the stoichiometric compositions TlGaS/sub 2/, TlGaSe/sub 2/, and T1InS/sub 2/, and their solid solutions, maximally enriched in thallium, the compositions of which were Tl /SUB 1.34/ GA /SUB 0.89/ S/sub 2/, Tl /SUB 1.31/ Ga /SUB 0.90/ Se/sub 2/, and Tl /SUB 1.15/ In /SUB 0.95/ S /SUB 2./ . Samples were synthesized from the elemental components of the following purities: gallium of V4 grade; indium of V4 grade; thallium of T1000 grade; selenium of special purity 22-4 grade, and sulfur of special purity garde. The compositions were checked by x-ray-phase-(DRON-0.5) and microstructural-analyses with simultaneous determination of the density and microhardness of the samples. It is found that the lattic parameter increases and the increase in the density and microhardness points to strengthening of the structure during the formation of the solid solutions.
