The analytical multi-3D model of the phase diagram of the Tl9GdTe6-Tl8Pb2Te6-Tl9BiTe6 system was obtained and visualized for the quasi-ternary and non-quasi-ternary high-temperature part. The analytical models of phase diagrams of the Tl9GdTe6 –Tl8Pb2Te6 and Tl9GdTe6 –Tl9BiTe6 systems were obtained in the "temperature – composition" coordinates. The boundaries of the liquidus and solidus surface of crystallization of solid solutions and the TlGdTe2 compound were obtained. The thermodynamic functions of mixing solid solutions were determined based on the model of regular solutions of non-molecular compounds. It was shown that solid solutions based on the ternary Tl9GdTe6, Tl8Pb2Te6, and Tl9BiTe6 compounds have thermodynamic stability in the entire concentration range and the temperature range T = 300–780 K.
