摘要：

Synthesis of the gamma-Ga2O3-Al2O3 solid solutions by spray pyrolysis was examined. Spherical particles were obtained using an aqueous solution of Al(NO3)(3) and Ga(NO3)(3) with HNO3. For Ga-rich composition, gamma-phase solid solutions were directly crystallized by the spray pyrolysis. For Al-rich composition, spray pyrolysis gave amorphous products unless a sufficient thermal energy was supplied during the spray pyrolysis. Subsequent calcination of the amorphous products gave gamma-Ga2O3-Al2O3 solid solutions. However, physical properties of the solid solutions were affected by the spray pyrolysis conditions.
