In the course of searching environmental friendly lead‐free relaxor ferroelectrics a complete phase diagram of barium zirconate titanate, Ba(Zr x Ti 1− x )O 3 system with compositions 0.00≤ x ≤1.00 has been developed based on their dielectric behavior. It has been shown that BaZr x Ti 1− x O 3 system depending on the composition, successively depicts the properties extending from simple dielectric (pure BaZrO 3 ) to polar cluster dielectric, relaxor ferroelectric, second order like diffuse phase transition, ferroelectric with pinched phase transitions and then to a proper ferroelectric (pure BaTiO 3 ). A comprehensive structure–property correlation of BaZr x Ti 1− x O 3 ceramics has been studied to understand the various ferroelectric phenomena in the whole phase diagram.
