Phase equilibria in the ternary Ga-Pt-Sb system

The phase relationships of GaSb in the ternary system Ga-Pt-Sb were studied within an isothermal section at 500 degrees C by means of X-ray diffractio n (XRD) and electron probe micro analyses (EPMA). Ternary phase reactions w ere determined using differential thermal analyses (DTA) in the platinum-po or area of the phase diagram. All experimental phase diagram data were comb ined to construct a complete reaction scheme (Scheil diagram) in the invest igated composition area and the liquidus surface was derived based on the r esults of the DTA measurements.
