Low-Temperature Synthesis of Mono-Phase Ultrafine Yttrium Aluminum Garnet by Sol-Gel Combustion Process

Abstract:

Ultrafine yttrium aluminum garnet (Y3Al5O12, YAG) powders were synthesized by sol-gel combustion process from a mixed solution containing aluminum and yttrium nitrates. The precursor and powders were characterized using X-ray diffraction, thermogravimetry-differential scanning calorimetry-mass spectrometry, and transmission electronic microscope. Mono-phase cubic powders were obtained at 900oC by directly crystallizing from amorphous materials and no intermediate phase was observed. The powders processed at 900oC were uniform and in good dispersity with average particle size of about 20 nm.
