The ternary system GeTeSe was investigated by differential thermal analysis, thermogravimetry, X-ray diffraction and scanning electron microscopy. The quasi-binary systems, various isoplethal sections and the liquidus surface of the system were constructed. The liquid-liquid miscibility gaps have been obtained. The principal results are summarized as follows. 1. No ternary compound appears in the system. 2. The GeSe2Te and GeTeGeSe2 junctions form true quasi-binary systems. 3. The reactions at the main invariant points are {A figure is presented} 4. Three liquid-liquid miscibility gaps exist: the first is situated entirely in the ternary system giving the monotectic reaction {A figure is presented} in the GeSe2Te quasi-binary system. The other liquid-liquid miscibility gaps are based on those occurring in the GeSe2Ge system. © 1980.
