The Numerical Modeling of the Composition and State of Aggregation of the Condensed Medium Formed in Heating the Bi2o3 Oxide in Argon

The paper presents the results of the thermodynamic modeling of the composition and state of aggregation of the condensed medium formed in a Bi2O3-Ar medium at 9.8066 × 10−2 MPa over the temperature range 300–1300 K. The possible presence of the Bi2O3, BiO, Bi2O5, and BiO2 oxides in the solid and liquid states was taken into account. Temperature-induced changes in the solid and liquid solution components (bismuth oxides in various states of aggregation) are discussed.
