Preparation and Characterization of Superfine YAG Powder Materials via the Co-precipitation Methods

摘要

YAG is widely applied as the structure materials and the functional materials because of some excellent performances in the chemistry. The pure superfine YAG powder materials are prepared via the co-precipitation method after calcining the precursor of YAG at 1100°C. The superfine YAG powders has the better dispersion, the particle size distribution range is narrow between 200 and 350nm. The superfine YAG mainly show near-spherical, and partly sintering behavior among the particles.
