In this paper we report samarium substituted Ba 0.80 Pb 0.20 Ti 0.90 Zr 0.10 O 3 (BPZT) ceramics. The material series with compositional formula Ba 0.80-x Sm x Pb 0.20 Ti 0.90 Zr 0.10 O 3 with x varying from 0 to 0.01 in the steps of 0.0025 was chosen for investigations. The material was synthesized by solid state reaction method. Reacted powders compacted in the form of circular discs were sintered at 1325°C. All the samples were subjected to X-ray analysis and found to be single phase. Dielectric behavior was studied as a function of frequency and temperature and Curie temperature (Tc) was determined. Tc was found to decrease with increasing x. The details are discussed and presented here.
