Abstract
Phase equilibria in the Se-rich part of the Pb-In-Se system have been inves tigated by metallographic examinations, DTA, DSC, XRD and EDX measurements. Two ternary phases were observed: S (Pb1.46In2.86Se5.71) and B ' (Pb0.8In3 .5Se5.7). The S compound was found to form congruently, while the B ' compo und forms incongruently. Reactions of alloys crystallisation are determined for the Se-rich part. Miscibility gaps which emerge from the In-Se and Se- Pb binary systems extend into the ternary system to form one gap across it. Reaction scheme for the PbSe-Se-InSe system is proposed.
