Study of Sintering Condition of Zirconium Rich PZT Cermics by Hydroxide Coprecipitaion

Abstract

Abstract: A wet procedure to prepare stoichiometric and homogeneous Zr rich PZT powders was described. The hydroxide precursor was prepared by coprecipitation from a mixed nitrate solution containing Pb²⁺, Zr⁴⁺, Ti⁴⁺ ions at pH 9. The precursor pellets were calcined at 550℃ for 0.5h and reactively sintered at 1130℃ for 2 h under hot-press, then a density of 98% theoretical density was obtained, as well as the samples exhibited good ferroelectrics properties.

Key words: Co-precipitation method, Zr rich PZT, reaction sintering, hot-press sintering
