Pb(Zr0.95Ti0.05)O3 (PZT95/5 for short) anti-ferroelectric nano-powder was prepared by a sol-gel method, and the effects of calcination temperature on the structural stability of perovskite for PZT(95/5) was investigated. Based on the results of TGA-DSC, the calcination temperature range of dried gel was identified as from 550 °C to 750 °C. XRD results illustrate that the peak intensity of the main crystalline phase increases gradually, while that of the impurity phase decreases, eventually disappears with the increasing of the calcination temperature T1. When calcined at 750 °C, single phase of perovskite for PZT (piezoelectric transition) (95/5) is formed. SEM observation shows that with the increasing of T1, the powder synthesized becomes finer and more uniform progressively. And when calcined at 750 °C, the average particle size of PZT(95/5) nano-powder is about 100 nm.
