characterizations of BNT ceramics synthesized by different techniques

Abstract

Bismuth Sodium Titanate (Na0.5Bi0.5TiO3) was prepared by the conventional solid state route as well as the chemical route. Calcination of the sample prepared through the solid state route was done at 7500C for 8 hours and of the sample prepared through the chemical route at 6000C for 6 hours. XRD of the samples was done in which a single perovskite phase was confirmed. The samples were sintered using the conventional sintering method at 11500C for
two hours and using the microwave sintering method at 11500C for 30 minutes with a heating rate of 400/min. SEM images of the samples were taken which showed dense microstructure and uniform grain size. Comparative study of dielectric properties of the samples was done.
PE loop measurements were done to confirm the ferroelectric naturte of the sample.
