Hydrothermal Synthesis and Characterization of Per ovskite PbTiOs3Powders from Different Precursors

Perovskite-type of PbTiO₃ fine powders which are homogeneous in physic-chemical properties has been hydrothermally synthesized from the different precursors. The borderline reaction conditions, such as temperature and time, for the formation of PbTiO₃ were established and the effect of the precursor on the particle properties was investigated. As a precursor, Pb-Tialko-carbonate xerogel dispersed in 2-methoxyethanol was found to be effective for the synthesis of the PbTiO₃ powders with a lower agglomeration and a simple mode of particle-size.
