Phase equilibria in the quasi-binary thallium(I) selenide-bismuth(III) selenide system

The phase equilibrium diagram for the system Ti 2 Se-Bi 2 Se 3 has been constructed from the results of thermal analysis. The diagram has been compared with that for the analogous system Tl 2 Te-Bi 2 Te 3 , as well as with that published earlier for the same Tl 2 Se - Bi 2 Se 3 system, delineated from the data obtained by other methods.
