Microwave-assisted synthesis of GaO(OH) and Ga2O3 nanorods

By Chitta Ranjan Patra, Yitzhak Mastai and Aharon Gedanken, JOURNAL OF NANOPARTICLE RESEARCH 6 (5): 509-518 OCT 2004

Since much of the consortium activity was concentrated on metallic oxide nanoparticles being the substrates for the sensing of gases, we have tried to synthesize this materials in small scale. The method by which they were synthesized is microwave dielectric heating.

Submicrometer sized gallium oxide hydroxide (GaO(OH)) and gallium oxide (Ga2O3) rods have been successfully fabricated on a large scale by refluxing an aqueous solution of Ga(NO3)(3) and NH4OH in a simple domestic microwave oven (DMO). The calcined product consists of submicrometer rods with diameters
of 0.4 - 0.5 microns and lengths of 5 - 5.5 microns.
