It was found that PLZT was easily reduced and the thickness of reduced layer had a linear relationship with the reduction time; The optimal conditions for PLZT were determined to be 950℃ for 1~5 hours; Reduced PLZT was composed of reduced and unreduced layer obviously and the reduced layer was transgranularly fractured while the unreduced ceramic was intergranularly fractured; Metallic lead and refractor oxides (PbO, ZrO2, TiO2, etc.) were found in the reduced layer, however, the crystal structure of PLZT was not found.
