Effects of Sintering Temperature on Structural and Electrical Properties of Fe³⁺ Doping PZT Ceramics

The influence of the sintering temperature on the structure and on the hysteresis loops of Fe³⁺ doped Pb(Zr_xTi_1-x)O₃ system has been investigated. Three compositions have been selected in the following mode: one in rhombohedral region, one in MPB region and one in tetragonal region have been obtained by solid state reaction technique. Sintering has been carried out at 1200⁰C and 1250⁰C respectively. The nature of the phases has been investigated in detail using X-ray diffraction analysis (XRD). All the sintered samples reveal a perovskite type structure. The surfaces have been lapped and metalized in order to obtaine the hysteresis loops at room temperature. The results showed a similar behaviour with “hard” PZT ceramics.
