Abstract Several of the physical properties of α-Bi2O3 have been studied in the temperature region above room temperature: the thermal expansion, the thermally stimulated current, the permittivity, the electrical resistance, and the specific heat. X-ray diffraction measurements and a thermogravimetric analysis have also been carried out. Several unusual properties in the physical properties of bismuth oxide have been detected in the temperature interval 450–570 K: exothermic maxima on the DTA and DSC curves, a small maximum and a sharp increase of the permittivity of the single crystal, a jump and a change of sign in the thermally stimulated current, and a sharp falloff of the electrical resistance of ceramic samples. At the same time, no appreciable changes in the monoclinic structure of α-Bi2O3 have been recorded in the indicated temperature interval.
