Dielectric behavior of Ba0.95Sr0.05TiO3 ceramics sintered by microwave

Here we report detailed dielectric studies carried out on a Barium strontium titanate (BST) (95:5) composition. The material was synthesized by conventional ceramic method and microwave processing, and the later technique resulted in material with high density, improved microstructure and dielectric properties. The dielectric properties were studied as a function of frequency and temperature and well-defined ferroelectric behavior of first order transition was observed. It follows Curie–Weiss law above transition temperature (paraelectric region). Curie temperature is slightly higher for microwave sintered (MS) material.
