Composite materials of (1-x)PZT-(x)Fe₂O₃, when x = 0.1, 0.3, 0.5, 0.7 and 0.9, were prepared by solid-state reaction technique. PZT powder was first synthesized with calcination temperature of 900 °C in air. Phase formation, densification, morphology and magnetic properties of (1-x)PZT-(x)Fe₂O₃ composites were investigated and discussed. The XRD technique was used to analyze the phase formation behavior. Fe₂O₃ reach phase was found with increasing Fe₂O₃ content. Interestingly, for high sintering temperature of 1100 ^oC, the major gramma - Fe₂O₃ phase was found for all Fe₂O₃ substitution in PZT system. Densities of the sintered specimens tend to decrease with increasing Fe₂O₃ content. In addition, the superparamagnetic behaviors were observed using a Vibrating Sample Magnetometer (VSM), which reached maximum value at x = 0.7. More importantly, Fe₂O₃ addition has been found to affect the phase formation, microstructure and ferromagnetic properties of PZT ceramics.
