摘要

0.8PMN-0.2PT solid solution ceramic was synthesized by combustion method using urea as fuel at different sintering temperature range 1100-1170°C. The resulting powder was characterized by XRD and SEM to confirm the phase and particle size. A good correlation was obtained between dielectric properties with structure, microstructure and density. The maximum dielectric constant for 0.8PMN-0.2PZN sintered at 1170°C is found to be 13345 with Curie temperature 100°C at 100 Hz.
