Abstract:

Computer Coupled Phase Diagrams and Thermochemical Data have been used to calculate the GeO2-MgO, GeO2-HfO2, GeO2-TiO2, GeO2-Al2O3, GeO2-CaO, GeO2-SiO2, TiO2-MgO, HfO2-SiO2, HfO2-MgO, HfO2-CaO, Al2O3-HfO2, HfO2-Y2O3, HfO2-TiO2, Ce2O3-Al2O3, ZrO2-HfO2, ZrO2-SiO2 ZrO2-CaO, Y2O3-MgO and Y2O3-CaO binary systems as well as isothermal sections in teh MgO-TiO2-SiO2, MgO-SiO2-GeO2, GeO2-MgO-CaO, HfO2-CaO-MgO, HfO2-SiO2-ZrO2 and HfO2-CaO-Y2O3 at temperatures between 700K and 3000K.
