These powders were calcined at 800°C for 4h and circular test specimens were prepared by uniaxial pressing. The specimens were sintered at 1150°C/2h, poled at 2kV/mm d.c. voltage and were characterized for dielectric, ferroelectric and piezoelectric properties. It was observed that the piezoelectric and ferroelectric properties initially increase up to 2mol% of ceria addition and then decrease with increase in ceria concentration. The diffusivity of the dielectric curves increases with increase in ceria concentration. The decrease in Curie temperature was observed from 173°C corresponding to pure PMN-PT to a temperature of 138°C for 10mol% of ceria addition.
