Monodispersed nanosized yttrium aluminum garnet (YAG) powder was synthesized via a mixed‐solvent thermal method using stoichiometric amounts of inorganic aluminum and yttrium salts. Pure‐phase YAG crystalline powder was obtained at low temperature (290°C) and low pressure (10 MPa). The resulting products were characterized by X‐ray powder diffraction (XRD), infrared, and transmission electron microscopy (TEM). XRD results showed that single‐phase YAG could be formed directly from an amorphous precursor at 280°C and become fully developed at 290°C. TEM images showed that the YAG powder particles in the study were basically spherical in shape and well‐dispersed with a mean grain size of about 60 nm.
