La doped BiFeO3:SrAlO3 samples were synthesized by sol-gel method. Composite was made to synthesise nano powder in order to improve electrical, optical and thermal properties. Goldschmidt tolerance factor for SrAlO3 is 0.9 which confirms this assembly to be a promising Perovskite. Investigations were carried out on samples where formation of false perovskite is verified by X-ray diffraction technique. The dielectric loss (tan δ) and conductivity (σ) were measured at room temperature as a function of the frequency (100 Hz – 25kHz). Structural and Electrical properties of this nanocomposite make them potential candidate in the field of thermoelectric energy devices.
