摘要
Mechanochemical process has been applied to the mixture of Y2O3 and Al2O3 in order to increase its reactivity. Yttrium aluminate garnet (YAG, Y3Al5O12) has been synthesized at 1000 degreesC from the milled mixture, which is significantly lower than that required by the conventional solid-state reaction process and comparable with that required by most of the chemical-based synthesis routes. The reduced formation temperature of the YAG phase is believed to be beneficial from the refined Y2O3 and Al2O3 as a result of the high-energy ball milling. (C) 2002 Elsevier Science B.V.
