Temperature Dependent Dielectric Properties of PB[(MG1/3NB2/3)1-XTIX]O3 for X= 0.25 Prepared By Solid State Reaction Method

Abstract

Relaxor ferroelectric 0.75PMN-0.25PT was synthesized by two-step solid state reaction method via columbite route. The final mixed and grinded compositions was calcined at 9200C for 2h and then sintered at 12000C for 6h. The XRD data show the perovskite phase of prepared material with reduced pyrochlore phase and the SEM micrographs shows the compact and dense grains. The dielectric measurement shows the temperature dependent nature having dielectric constant 13189.44 at Curie temperature (Tc).
