Structure-property phase diagram of BaZrxTi1-xO3 system

In the course of searching environmental friendly lead-free relaxor ferroelectrics a complete phase diagram of barium zirconate titanate, Ba(ZrxTi1-x)O-3 system with compositions 0. 00 <= x <= 1.00 has been developed based on their dielectric behavior. It has been shown that BaZrxTi1-xO3 system depending on the composition, successively depicts the properties extending from simple dielectric (pure BaZrO3) to polar cluster dielectric, relaxor ferroelectric, second order like diffuse phase transition, ferroelectric with pinched phase transitions and then to a proper ferroelectric (pure BaTiO3). A comprehensive structure-property correlation of BaZrxTi1-xO3 ceramics has been studied to understand the various ferroelectrie phenomena in the whole phase diagram.
