Glass formation and properties of chalcogenide systems (XXII) the phase diagram of the system PbSeGeSe2 and on the compound Pb2GeSe4

Adalbert Feltz, Werner Ludwig, L. Senf, Christian Simon

Abstract

Abstract The phase diagram of the system PbSeGeSe2 is studied by X‐ray analysis and DTA. Pb2GeSe4 is the only compound which is formed in the system. It melts incongruently at 590 ± 4°C. The formation of Pb2GeSe4 as a definite compound is supported by studying the phase relations in the corresponding area of the ternary system PbSeGeSeGeSe2.
