Nanopowder of Ba0.7Ca0.3TiO3 (BCT) lead free ferroelectric ceramic was synthesized by hydroxide co-precipitation method. As-synthesized powder is sintered using the microwave sintering technique at different temperature 1100°C and 1200°C. Sintered ceramic samples were investigated for its structural, morphological, and temperature dependent dielectric properties. Structural analysis confirms biphasic crystal structure, tetragonal phase corresponding to BaTiO3 lattice and orthorhombic phase resulting from the CaTiO3 lattice. Scanning electron microscope images reveals the formation of grains with higher density. Ferroelectric-Paraelectric transition (Tc) of the material shifts towards higher temperature (Tc ~ 155°C) with maximum dielectric constant and low loss tangent.
