Abstract

Structural change of bismuth oxide (Bi₂0₃) was studied in situ by high-temperature neutron and synchrotron powder diffraction techniques. Crystal structure was refined by Rietveld analysis of neutron diffraction data. The nuclear density distribution of δ-Bi₂O₃ was obtained by maximum entropy method/Ritveld analysis. The position of oxygen atoms distributed forming tetrahedra.
