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...

Recientemente otros materiales basados en óxidos de cinc y bismuto han mostrado un gran potencial para su uso en aplicaciones como dieléctricos a frecuencias altas, renovando el interés por dicho sistema binario. El objetivo del presente trabajo es realizar una evaluación termodinámica del diagrama de fases consistente para el sistema Bi2O3-ZnO teniendo en cuenta la información experimental existente del mismo.
