Abstract: 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.
