摘要：

The phase diagram of the quasiternary system Ga2Te3/Hg3Te3/In2Te3 for the temperature range 650 < T/K < 900 was investigated by X-ray diffraction, by DTA measurements and by electron microprobe analysis. It is shown that ordered structures are formed at special concentrations of structural vacancies. Depending on temperature and concentration, continuous order-disorder transitions could be detected. Besides structural miscibility gaps and a three-phase region, there occurs also a miscibility gap within an ordered region.
