Аннотация:

Ellipsoid-shape acid-resistant microparticles of β-Ga2O3 are synthesized as a result of chemical reaction of gallium nitrate and ammonia in an aqueous solution with subsequent annealing of received sediment in air. It is shown that particle size depends in non-monotonous manner on the molar ratio of reacting substances. The maximum value of length and diameter (1718 ± 291 nm and 746 ± 198 nm, respectively) is obtained at ammonia to gallium nitrate ratio of 9:1. A decrease in particle size is observed both with reducing and increasing of the ratio. The particles have a layered structure with layer thickness 30 ± 5 nm.
