Abstract:Using stearic acid,lead acetate and tetrabutyl titanate as raw materials,the raw powder of PbTiO 3 nanocrystalline was synthesized by stearic acid gel method (SAG). The raw powder was sintered in the apparatus improved by us and the calcining temperature was controlled automatically. The first stepsinter was done in nitrogen atmosphere. The PbTiO 3 nanocrystalline which had good repeatability could be obtained after the second step sinter by controlling the flow of nitrogen and oxygen. The synthesis was investigated by DTA,TG and XRD. The size and shape was tested by TEM.The nanocrystalline PbTiO 3 sample was also characterized by IR.
Keywords:PbTiO  3  nanocrystalline  stearic acid  gel method
