摘要：

The phase diagram of the ZnO-SnO2 system at 800-1600 degrees C was experimentally investigated using the classical equilibration/quenching method and differential thermal analysis (DTA) followed by X-ray diffraction (XRD) phase analysis and electron probe micro-analysis (EPMA). Sealed platinum capsules were employed to prevent the evaporation of ZnO and SnO2 in the experiments. Based on new experimental phase diagram data and all available data in literatures, the binary ZnO-SnO2, SnO2-TiO2, and ZrO2-TiO2 and the ternary ZnO-SnO2-TiO2 system was thermodynamically optimized using the CALculation of PHAse Diagram (CALPHAD) method to prepare a set of Gibbs energies of all phases within the binary systems which can be utilized to predict unknown phase equilibria and thermodynamic properties in the system.
