Gallium(III) oxide - Wikipedia
Gallium trioxide is precipitated in hydrated form upon neutralization of acidic or basic solution of gallium salt. Also, it is formed on heating gallium in air or by thermally decomposing gallium nitrate at 200–250 °C. Crystalline Ga 2 O 3 can occur in five polymorphs, α, β, γ, δ, and ε.
mp-886: Ga2O3 (monoclinic, C2/m, 12) - Materials Project
Ga2O3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. 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.

Nano-structured phases of gallium oxide (GaOOH, α-Ga
2020年2月4日 · The crystal structure of γ-Ga 2 O 3 is known as a cation-deficient spinel structure and obeys the partial occupancy of Ga 3+ ions at, both, octahedral and tetrahedral sites [25,26,27]. Moreover, the simulated structure of γ-Ga 2 O 3 was constructed by choosing the initial structure model of γ-Al 2 O 3 [ 32 , 33 ].
