Thermodynamic study of the rich-Bi2O3 region of the Bi2O3-ZnO system
[EN] Precise knowledge of the Bi2O3-ZnO system is fundamental to control the functional microstructure of ZnO-based varistors. Also the potential applications of materials based on ZnO and Bi2O3 as dielectric materials in the high frequency range have renewed the interest in this binary system. The...

| Summary: | [EN] Precise knowledge of the Bi2O3-ZnO system is fundamental to control the functional microstructure of ZnO-based varistors. Also the potential applications of materials based on ZnO and Bi2O3 as dielectric materials in the high frequency range have renewed the interest in this binary system. The aim of the present work is to carry out a thermodynamic analysis of the Bi2O3-ZnO phase diagram, taking into account the existing experimental information. Thermodynamic calculation has been performed according CALPHAD methodology (CALculation of PHAse Diagrams), using the software Thermo-Calc. |
