Abstract
The Raman scattering spectra of isostructural Bi2O3 and Bi1.8Tm0.2O3 in the course of heating have been investigated. It is shown that the sequences of structural changes with increase in temperature differ: α → δ and δ* → β → δ, respectively. In the high‐temperature region, the structure takes the form of a disordered cube irrespective of the previous history of specimens.
