The solid solutions (BiFeO_{3})_{1-x}(BaTiO_{3})_{x} (x=0, 0.1, 0.2, 0.3, 0.4, and 0.5) have been synthesized adopting a solid state sintering route. Well crystalline phase of (BiFeO_{3})_{1-x}(BaTiO_{3})_{x} ceramics at different level of x has been optimized at sintering temperature of 950°C for 2 h. Dielectric, polarization and magnetocapacitance properties were investigated for different content level of BaTiO_{3}. Dielectric constant increased with increasing concentration of BaTiO_{3} up to x=0.3 for all the frequencies of 10, 100, and 1000 kHz. Dielectric loss in the material is attributed to space charges, interfacial and dipolar polarizations. Measurements of P-E loop indicated evident ferroelectricity in all samples. Well formed grain with varying grain sizes and nearly uniform shape was found for ceramics samples.
