Phase-pure Y3Al5O12 powder was obtained by precipitating the YAG sol with an aqueous dilute ammonia solution followed by calcination at 1100 degrees C. TG/DTA analysis showed an exotherm at 938 degrees C attributed to formation of YAG phase and weight loss of 44% at 1000 degrees C. XRD and FT-IR analysis showed that phase-pure YAG can be formed through noncrystalline and metastable hexagonal YAlO3 without forming either yttrium or aluminum formate intermediate.
