PHASE EQUILIBRIA IN TlS–TlAsS2 AND Tl3AsS3–S SYSTEMS
The results of research of phase equilibria on TlS–TlAsS2 and Tl3AsS3–S sections of system Tl–As–S using methods DTA, XRD and EMF are presented. The formation of congruent melting ternary compound Tl3AsS4 (695 К) is confirmed. Compounds Tl9As3S13 and Tl3AsSp6, earlier specified in the literature have not been confirmed.
Keywords : the TlS–TlAsS2, Tl3AsS3–S systems, phase diagram, sulfides of arsenic-thallium
