Tohoku Univ. Technology： Method for producing Gallium oxide：T19-388
Low-cost, low-temperature, and simple manufacturing processes
γ-Gallium oxide (γ-Ga2O3) is one of the metastable structures of gallium oxide and has excellent catalytic properties. However, it was difficult to be synthesized. In the conventional method for producing γ-Ga2O3, gallium nitrate hydrate was dissolved in distilled water with urea and baked at 500ºC. However, this method required a facility for high-temperature treatment and had a problem of increasing production costs such as equipment costs. The present invention makes it possible to provide a method for producing gallium oxide at a low temperature and a simple process, thereby reducing production costs. It is characterized in that a raw material solution containing liquid gallium and a reducing agent is irradiated with ultrasonic waves. Thus, particles of gallium can be refined, and particles having crystals of γ-Ga2O3 can be formed on the surface thereof. As a result, the baking process and the complicated separation and cleaning process are not required, the manufacturing cost is reduced, and γ-Ga2O3 can be produced by a simple process at a low temperature.
