【Abstract】 Perovskite PZT95/5 ceramics is prepared by the conventional technique from a mixture of such oxides as Pb3O4, ZrO2 and TiO2 and the dopant of Nb2O5. Synthesis and sintering technique is optimized by orthogonal test, and influence of regular changes of synthesis temperature and time, sintering temperature and time, heating rate and sintering atmosphere for the powders on ceramic densification is systematically analyzed. The results show that,of all the affecting factors,synthesis temperature and sintering temperature are of great significance.更多还原
