Lead-freeBaTiO3-basedmaterials is the replacement of lead-based materials for various dielectric applications. These materials having excellent piezoelectric, pyroelectric and ferroelectric properties in comparison of lead-based counterparts. In this article, the role of Cerium dopant on microstructural and dielectric performance of BaCexTi1-xO3 (BCT) ceramics with compositions x=0, 0.1, 0.12 and 0.15 is investigated in detail. A diffuse phase transition is typical for all the Ce doped compositions, with a substantial reduction of the Curie temperature towards room temperature. The performance of BaCe0.15Ti0.85O3 was good with respect to other samples.
