摘要: Yttrium aluminium garnet (Y 3 Al 5 O 12 , YAG) is an important material used as a laser host and in phosphors. YAG powders are conventionally synthesized by solid-state reaction processing using Y 2 starting materials. The process usually requires high calcination temperatures to eliminate intermediate phases. temperature inevitably leads coarsening of the microstructure and, thus low sinterability powders. As result, extremely sintering needed order obtain translucent or transparent ceramics. Various wet-chemical methods have successfully reduced Both ammonium hydroxide carbonate were precipitant for synthesis via co-precipitation process. In this study, was selected produce from solutions yttrium nitrates precipitation. effect molar ratio between source salt on yield composition resultant precipitates, evolution precursors with investigated.
