Neodymium-doped yttrium aluminum garnet (Y3-xNdxAl5O12) is one of the most important materials for laser applications.After the first Nd:YAG ceramic laser oscillation was realized with a ceramic by the solid-state process [1], many kinds of wet chemical synthesis routes have been studied in the preparation of fine powders for ceramics fabrication, such as numerous sol-gel methods [2], homogeneous precipitation [3], co-precipitation methods with ammonium hydrogen carbonate (AHC) [4] or ammonia [5] as precipitant, solvothermal methods [6].
