  4. Abstract:
  5. A new and effective hot milling system was designed and applied to the synthesis of PbZr0.95Ti0.05O3 (PZT) powder. PbO, ZrO2 and TiO2 powders were used as starting materials and hot milled at various temperatures ranging from 10 ̊°C to 800 ̊°C. The obtained powders were characterized by X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM). Results indicated that pure, crystalline, and fine PZT powders with the average particle size of 170 nm can be successfully synthesized directly after a relatively short synthesis time of 12 h at lower temperature of 800 ̊°C by the hot milling technique. In contrast to this method, this study demonstrates that conventional solid-state synthesis route, which includes milling and subsequent thermal annealing, would not give rise to the synthesis of pure PZT powder, indicating the simultaneous heating and milling effectively promotes formation of the perovskite PZT in the hot milling process. Finally, the results show that the hot milling method is a simple and effective approach for the large-scale production of PZT powders. © 2019 Elsevier Ltd and Techna Group S.r.l
