This paper describes the synthesis of multiferroic BiFeO₃ ceramics was prepared by solid state reaction and high energy ball milling method. The structural studies was carried out by using an X-ray diffraction pattern and demonstrated that the BiFeO₃ ceramic crystallizes in a rhombhohedral perovskite phase. The ferroelectric hystersis loop measured at room temperature demonstrates a lossy loop with unsaturated behavior and symbolize a partial reversal of polarization. A dielectric constant with temperature measurement for BiFeO₃ ceramic represents an anomaly around 350^oC for all frequencies and intimately associated with antiferromagnetic to paramagnetic phase transition (TN) of BiFeO₃.
