WebGa₂O₃ crystallizes in the monoclinic C2/m space group. There are two inequivalent Ga³⁺ sites. In the first Ga³⁺ site, Ga³⁺ is bonded to six O²⁻ atoms to form GaO₆ octahedra that share corners with seven equivalent GaO₄ tetrahedra and edges with four equivalent GaO₆ octahedra. There are a spread of Ga–O bond distances ranging from 1.94–2.08 Å. In the …
Webthe air reactor). The stable phases at low temperature are hematite and bixbyite, both with the general formula (Fe 1−xMn x)2O3, whereas the spinel phase (Fe 1−xMn x)3O4 is stable at high temperature. There are also two-phase areas in which both forms i.e. bixbyite/hematite and spinel, coexist at intermediate temperatures.
