摘要：

A complete literature review, critical evaluation, and thermodynamic modeling of the phase diagrams and thermodynamic properties of all oxide phases in the binary systems B2O3-SiO2 and B2O3-Al2O3 have been performed. The molten oxide is described by the Modified Quasichemical Model. Discrepancies in the available experimental data have been resolved and an optimized set of self-consistent thermodynamic functions of all phases has been obtained. This thermodynamic database can be used with the FactSage (TM) thermodynamic computing system to calculate all thermodynamic properties and phase equilibria from 25 degrees C to above the liquidus temperatures at 1 atm of total pressure and over the entire composition range.
