Subsolidus phase relations in the ZnO–WO 3–Bi 2O 3 system

Abstract

The subsolidus phase relations of the ternary system ZnO–WO 3–Bi 2O 3 were investigated by means of X-ray diffraction (XRD). Six binary compounds and seven 3-phase regions were determined, and no ternary compounds were found in this ternary system. The phase diagram of pseudobinary system ZnO–Bi 2WO 6 was also constructed through XRD and differential thermal analysis (DTA) methods, which forms eutectic system with eutectic temperature about 945 °C, the corresponding eutectic component is 35 mol% ZnO and 65 mol% Bi 2WO 6.
