摘要：Tabular PE-PbTiO3, spherical PY-PbTiO3, and acicular PX-PbTiO3 powders were hydrothermally synthesized from triethanolamine(TEA)-complexed precursor; clubbed PE-PbTiO3 powders were obtained from diethanolamine(DEA)-complexed precursor. The effects of pH of the hydrolyzation as well as complexing agents including TEA, DEA, and MEA(monoethanolamine) on the structure and the morphology of PbTiO3 powders are discussed. The optimal conditions for hydrothermal syntheses of acicular and clubbed PbTiO3 powders have been established. The products were characterized by means of XRD, TEM and other techniques.
