The character of the interaction in the TlAs2Se3Te–TlAs2Te3Se system was studied by the methods of DTA, RFA, MSA, and also by measuring the microhardness and determining the density. State diagram of the system was constructed. It was established that the TlAs2Se3Te–TlAs2Te3Se system is partially a quasibinary section of the quaternary As, Tl//Se, Te system. One congruently melting compound TlAs2Se2Te2 is formed in the system at 548 K. Solid solutions based on TlAs2Se3Te at room temperature reach up to 10 mol % TlAs2Te3Se, and solid solutions on the basis of TlAs2Te3Se are practically not detected. All the samples obtained are vitreous.
