Abstract
The Ga2O3-SnO2-ZnO (GSZO) system has been studied by Knudsen effusion mass spectrometry (KEMS) in the temperature range 1305-1495 K. The incongruent character of vaporization processes in the whole composition range of the GSZO system was observed. The main thermodynamic characteristics of heterogeneous equilibria in the system have been determined, as well as the standard enthalpies of reactions involving Zn2SnO4 and ZnGa2O4 spinels. A p–x vertical section of the phase diagram of the GSZO system has been plotted along the GaO1.5 and SnO2 equimolar ratio line.
期刊介绍：
The most trusted journal for phase equilibria and thermodynamic research, ASM International''s Journal of Phase Equilibria and Diffusion features critical phase diagram evaluations on scientifically and industrially important alloy systems, authored by international experts.
The Journal of Phase Equilibria and Diffusion is critically reviewed and contains basic and applied research results, a survey of current literature and other pertinent articles. The journal covers the significance of diagrams as well as new research techniques, equipment, data evaluation, nomenclature, presentation and other aspects of phase diagram preparation and use.
Content includes information on phenomena such as kinetic control of equilibrium, coherency effects, impurity effects, and thermodynamic and crystallographic characteristics. The journal updates systems previously published in the Bulletin of Alloy Phase Diagrams as new data are discovered.
