- Abstract
The dielectric, piezoelectric and electrical properties of relaxor ferroelectric 0.65PMN-0.20PZT-0.15PT ceramic as a function of sintering temperatures was investigated. X-ray diffraction shows that with increasing temperature from 700 °C to 800 °C the pyrochlore unwanted phase reduces and at 850 °C the single phase of perovskite be formed. The studies and reviews reveal that the outstanding electrical properties are obtained with this composition near the morphotropic phase boundary (MPB). P-E hysteresis loops emphasize that the synthesis optimum temperature is 1250 °C and observed that the best temperature that led to improved properties of dielectric constant, polarization and piezoelectric coefficients is this temperature.
