The massive transformation in bismuth oxide-based ceramics was investigated. The kinetics of the massive transformation was investigated under isothermal conditions using x-ray diffraction (XRD), reflected optical microscopy, transmission optical microscopy, transmission electron microscopy (TEM), electron-probe microanalysis (EPMA) and the measurement of ionic conductivity. A study of the Gd2O3-Bi2O3system showed that a massive transformation occured inside a two-phase field shedding some light on a controversial point. The transformation kinetics suggested that ceramic systems were better suited to investigate salient features of the massive transformation theories, which were developed for metallic alloys.
