In the present investigation, a solid solution of BiFeO3 and NiTiO3 i.e., (Ni0.45Ti0.45Fe0.10) O3 (abbreviation is BNTF) have been synthesized using a solid-state reaction technique. Structural and dielectric properties of BNTF ceramics have been studied in details to understand their properties. Preliminary X-ray diffraction analysis confirm the formation of a new system, which is different from that of its parent compounds. Substitution of a small amount of NiTiO3 into BiFeO3 enhances dielectric and ferroelectric properties, and reduces electrical leakage current or tangent loss. It was shown by XRD that at room temperature structure of the compound is of single-phase with tetragonal symmetry. Some electrical characteristics (dielectric constant and loss) studied over a wide frequency (1 kHz-1 MHz) and temperature (25-400 °C) ranges have provided many more interesting information useful for devices.
