Preparation of Gd _3Ga_5O_(12 )(GGG) Polycrystalline Material by Liquid-phase Co-deposition Synthesis Method

A gadolinium gallium garnet (Gd3Ga5O12,GGG) polycrystalline material was prepared by a liquid-phase co-deposited synthesis method. The optimized procedure and the conditions for preparing the GGG polycrystalline material by the liquid-phase method were reported. The effects of the compositional proportion of Gd2O3 and Ga2O3, pH value of titration, synthesis temperature and sintering time on preparing GGG polycrystalline powders were also discussed. By comparison with the preparation of GGG polycrystalline material by solid-state reaction process, the liquid-phase synthesis method possesses the merits of lower synthesis temperature and shorter sintering time. At the same time, the GGG polycrystalline material prepared by the liquid-phase co-deposited method has high uniformity and exact stoichiometric composition.
