The borderline reaction conditions, such as temperature and time, for the formation of PbTiO 3 were established and the effect of the precursor on the particle properties was investigated. As a precursor, Pb Ti alko carbonate xerogel dispersed in 2 methoxyethanol was found to be effective for the synthesis of the PbTiO 3 powders with a lower agglomeration and a simple mode of particle size.展开更多
