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°C by means of X-ray diffraction (XRD) and electron probe micro analyses (EPMA). Ternary phase reactions were determined using differential thermal analyses (DTA) in the platinum-poor area...

Zusammenfassung:	The phase relationships of GaSb in the ternary system Ga–Pt–Sb were studied within an isothermal section at 500°C by means of X-ray diffraction (XRD) and electron probe micro analyses (EPMA). Ternary phase reactions were determined using differential thermal analyses (DTA) in the platinum-poor area of the phase diagram. All experimental phase diagram data were combined to construct a complete reaction scheme (Scheil diagram) in the investigated composition area and the liquidus surface was derived based on the results of the DTA measurements.
