摘要：

The SrO-MgO and SrO-SiO2 systems have been critically evaluated based upon available phase equilibrium and thermodynamic data, and optimized model parameters have been obtained giving the Gibbs energies of all phases as functions of temperature and composition. The liquid solution has been modeled with the Modified Quasichemical Model to account for short-range-ordering. The results have been combined with those of previous optimizations of the MgO-SiO2 system in the optimization of the SrO-MgO-SiO2 system.
