Yttrium aluminum garnet (YAG) powders were synthesized via chemical precipitation, both with and without the addition of ammonium sulfate as a dispersant. The impact of the dispersant on the particle size distribution of YAG powders calcined at various temperatures was investigated. Powder morphology was analyzed using scanning electron microscopy (SEM), revealing significant differences in both morphology and particle size depending on whether the dispersant was present. The kinetics of phase transformations in the ceramic powders, with and without ammonium sulfate, were thoroughly examined using X-ray diffraction (XRD) and simultaneous thermal analysis (STA). Based on the data obtained, a novel mechanism was proposed for reducing agglomeration in YAG ceramic powders through the use of ammonium sulfate as a dispersant. This mechanism entails the formation of intermediate phases, namely yttrium sulfate and yttrium oxysulfate, followed by their gradual decomposition to yield the garnet phase.
