Thermodynamic assessment of the PbO-V2O5 system

Based on the experimental phase equilibria and thermodynamic data, a critical evaluation and thermodynamic assessment of the PbO-V2O5 system has been performed. The liquid phase is described by the modified quasichemical model, which takes short-range ordering in liquid solution into account. All intermediate phases are treated as stoichiometric compounds. A set of self-consistent thermodynamic functions for all phases in the PbO-V2O5 system is obtained. The available phase equilibria and thermodynamic data are reproduced well within experimental error limits.
