Preparation of PLZST with Complex Perovskite Structure by Coprecipitation

Abstract

Abstract: A modified chemical coprecipitation route to synthesize homogeneous lead lanthanum zirconate stannate titanate (PLZST) precursors was described. The formation process of PLZST from the
precursors was monitored by thermal analysis, and the phases were characterized by X-ray diffraction. Compared with the solid-state reaction of constituent oxides, the PLZST powders prepared by coprecipitation
have high purity, homogeneous and low synthesis temperature. The formation temperature of single perovskite PLZST is as low as 700℃ in this method of preparation. Pb content analyzed by
chemical methods indicates that the loss of Pb in PLZST synthesized at low temperature is minimal.

Key words: coprecipitation, PLZST, perovskite
