摘要: Abstract Yttrium aluminum garnet (YAG) powder was successfully synthesized by a novel solid state reaction method. The starting materials including: yttrium oxide (Y 2 O 3 ), boehmite (AlOOH) and cerium chloride (CeCl ·7H O) are pre-aged at pH 1, 3, respectively, before calcining. According to the experimental results, case of pre-aging 1 is best condition for formation YAG powder. particle size Y AlOOH reduced 1. It induces shorten diffusion distance reaction. process leads via more easily. emission intensity product increased decrease pH, increase calcination temperature heating time.
