Study of Dielectric behavior and dielectric loss of PbZrO3: Temperature dependence

The Perovskites PbZrO3 is widely used in communication electronics, microelectronics, and anti-ferroelectric material. The dielectric behavior of the Perovskites PbZrO3 is compressed in pellet from have been studied using capacity measuring unit Zeinith M92 A were synthesized by solid state reaction technique. The dielectric constant (??') and dielectric loss (?’’?) of the compounds have been studied at 1 kHz, 10 kHz and 100 kHz in the temperature range of 300K to 1200K. The dielectric constant of PbZrO3 show rapidly increases above 700K and 8500K respectively. After this temperature the dielectric constant decreases. The dielectric loss also shows similar behaviour as dielectric constant and it is also temperature dependent.
