YAG Powder Synthesis and Characteristics
Two techniques were applied to prepare single phase YAG powder: i) citrate process based on complexing properties of citric acid with isopropyl alcohol additive as esterification agent and ii) co-precipitation from relative nitrates solution with ammonia. At low temperature heat treatment both techniques lead to the X-ray amorphous bodies. Their calcination at elevated temperatures results in single-phase YAG powder. Differences in the behaviour of the amorphous precursors during heat treatment will be shown.
