The nanocrystalline Pb 1− x Gd x (Zr 0.53 Ti 0.47 ) 1− x /4 O 3 (where x =0.04, 0.08 and 0.12) (PGZT) has been synthesized by a high-energy ball milling (mechanical activation synthesis) followed by sintering. The nanocrystalline PGZT obtained by this route has exceptionally high dielectric constant. X-ray diffraction studies showed that PGZT has tetragonal structure at all the compositions studied. Detailed studies of dielectric properties of PGZT as a function of temperature show a non-relaxor type ferroelectric diffused phase transition.
