摘要：
In the present work, a series of ZrO2-TiO2-SrO ceramic samples were prepared through solid-state reactions, and the phase relationships at 1473 K were systematically characterized. For the TiO2-SrO binary system, the presence of Sr4Ti3O10 was confirmed and the binary system was reassessed through CALPHAD method by using both the latest experimental data and first-principles calculations. The thermodynamic parameters of the TiO2-SrO system were combined with those of the ZrO2-TiO2 and ZrO2-SrO systems, and a set of self-consistent thermodynamic parameters of the ZrO2-TiO2-SrO system was optimized according to our measurements. Finally, the isothermal sections at 1473 K and 1733 K, the vertical section of SrTiO3-SrZrO3 and the liquidus surface projection were calculated. The calculated results agree well with the available experimental data, which proves the self-consistency and reliability of the present thermodynamic database.
