Polycrystalline, Neodymium doped, yttrium aluminum garnet Nd:YAG is a functional materials for solid‐state lasers. The synthesis of Nd:YAG powders requires a strict control of the precursor reactivity and composition. Sol‐gel citrate‐based methods increase the chemical homogeneity and reactivity of the precursor powder. Calcination performed around 900 °C leads to the formation of pure YAG phase at temperatures much lower than the temperature required for the solid‐state reaction (1600 °C).
