Abstract In-situ Raman spectroscopy was employed to investigate PLZT ceramics (atomic ratio Zr/Ti=52/48, doped with small amount of La, Mn and Nb) at different temperatures. The observed Raman spectra were modified by the Bose population factor, and curve-fitted by the damped-harmonic-oscillator model and Gauss distribution function. Accordingly, the variations of Raman shifts and intensities of soft modes with temperatures were obtained. It confirmed that two types of phase transitions near morphotropic phase boundary (MPB) occurred at 240℃ and 360℃, respectively, when the temperatures increased from 47 to 600℃, indicating possible presence of mixed phases in PLZT ceramics. The effects of pre-polarization on phase transition are briefly discussed based on a comparison between the changes in Raman shift and intensity of soft mode observed with the unpoled powders and poled bulk specimens.

Key words: morphotropic phase boundary ferroelectric ceramics phase transition in-situ Raman spectroscopy
