Nanocrystalline Pb(Zn 1/3 Ta 2/3 )O 3 (PZTa) of perovskite structure, which cannot be synthesized by either the conventional solid‐state reaction of mixed oxides or wet chemistry routes, has been successfully synthesized via a mechanical activation route. The effects of PbTiO 3 (PT) doping in PZTa on the phase formation, thermal stability of the nanocrystalline perovskite phase, and dielectric properties of the resulting PZTa–PT are studied. PZTa doped with a low PT content exhibited a diffuse phase transition, while those with high PT contents demonstrated an expected sharp phase transition at the Curie temperature.
