Freestanding crystalline PbZrO3 nanoparticles with an average size of 15 nm were synthesized by the modified sot gel method and characterized by X-ray diffraction and electron microscopy. Dielectric studies indicated that the paraelectric to antiferroelectric phase transition in the PbZrO3 nanoparticles was observed around at 205 degrees C which was at 233 degrees C for PbZrO3 bulk material. A single leaky ferroelectric loop was observed instead of an antiferroelectric double hysteresis loop which may be because of the defects such as grain boundaries and the pores in the sample because the sample was not sintered at higher temperatures to retain the nanoscale dimension of the PbZrO3 particles.
