Abstract
PLZT (7.45/71/29) ceramics with fully dense microstructure and high transmittance were fabricated by a hot‐press sintering method. The effects of temperature on the phase structure, ferroelectric property, and electric‐induced light scattering performance of the PLZT ceramics were examined and analyzed. XRD patterns indicated that the PLZT sample tended to transform from rhombohedral phase to tetragonal phase with the temperature increasing. And the temperature‐dependent ferroelectric hysteresis behavior of the PLZT sample revealed the conversion of a saturated square hysteresis loop to a double‐loop‐like hysteresis loop, accompanied with the significant reduction in coercive field and remnant polarization. Depending on the temperature, the PLZT sample exhibited three different kinds of electric‐induced light scattering performance.
