Abstract
The phase diagram of the ZnO-SnO2 system at 800–1600 °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.
期刊介绍：
Physics and Chemistry of Minerals is an international journal devoted to publishing articles and short communications of physical or chemical studies on minerals or solids related to minerals. The aim of the journal is to support competent interdisciplinary work in mineralogy and physics or chemistry. Particular emphasis is placed on applications of modern techniques or new theories and models to interpret atomic structures and physical or chemical properties of minerals. Some subjects of interest are:
-Relationships between atomic structure and crystalline state (structures of various states, crystal energies, crystal growth, thermodynamic studies, phase transformations, solid solution, exsolution phenomena, etc.)
-General solid state spectroscopy (ultraviolet, visible, infrared, Raman, ESCA, luminescence, X-ray, electron paramagnetic resonance, nuclear magnetic resonance, gamma ray resonance, etc.)
-Experimental and theoretical analysis of chemical bonding in minerals (application of crystal field, molecular orbital, band theories, etc.)
-Physical properties (magnetic, mechanical, electric, optical, thermodynamic, etc.)
-Relations between thermal expansion, compressibility, elastic constants, and fundamental properties of atomic structure, particularly as applied to geophysical problems
-Electron microscopy in support of physical and chemical studies
-Computational methods in the study of the structure and properties of minerals
-Mineral surfaces (experimental methods, structure and properties)
