Abstract
AbstractThe phase relationships of GaSb in the ternary system Ga‐Pd‐Sb were studied for an isothermal section at 500°C by means of X‐ray diffraction (XRD) and electron probe micro analyses (EPMA). Eight invariant ternary phase reactions, i.e. three quasibinary eutectic reactions, three ternary transition reactions and two ternary eutectics were identified by means of differential thermal analyses (DTA). All experimental phase diagram informations 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. The gallium‐rich part of the limiting binary Ga‐Pd system was reinvestigated by means of DTA and XRD.
