Ultrahigh purity beta gallium oxide microstructures

Ultrahigh purity gallium oxide (Ga2O3) microstructures were synthesized via hydrothermal method using gallium nitrate hydrate and ammonium hydroxide to synthesize gallium hydroxide, followed by calcination at a 1000 °C. Scanning electron microscopy revealed that following calcination, the material s...

Summary:Ultrahigh purity gallium oxide (Ga2O3) microstructures were synthesized via hydrothermal method using gallium nitrate hydrate and ammonium hydroxide to synthesize gallium hydroxide, followed by calcination at a 1000 °C. Scanning electron microscopy revealed that following calcination, the material showed a large number of microparticles with lengths of ≤1 μm and diameters of 250–350 nm. Energy-dispersive X-ray spectroscopy, X-ray diffraction, Raman spectroscopy, infrared spectroscopy, and X-ray photoelectron spectroscopy analyses indicated the high purity and near-stoichiometric composition of the material. The results also confirm the formation of β-phase Ga2O3 with high crystallinity.
