Subsolidus phase relations in the ZnO–P 2O 5–WO 3 system

Abstract

The subsolidus phase relations of the ZnO–P 2O 5–WO 3 ternary system were investigated by means of X-ray diffraction (XRD). No ternary compound was found in this ternary system, while five binary compounds were obtained and six compatibility triangles were determined. The phase diagram of pseudobinary system Zn 3(PO 4) 2–ZnWO 4 was also constructed through XRD and differential thermal analysis (DTA) methods, which forms eutectic system with eutectic temperature about 990 °C. The corresponding eutectic component is 30 mol% ZnWO 4 and 70 mol% Zn 3(PO 4) 2.
