Abstract:Calcium modified lead titanate nanocrystal materials have been prepared by using a sol\|gel method. Different thermal treatment conditions have been used for the research of the crystalline structure of Pb\-\{\%1-x\%\}Ca\-\%x\%TiO\-3 powders. The lattice parameters and \%c/a\% ratios were determined by using XRD method. The grain sizes of powders were detected by TEM photographs and X\|ray diffraction. The influence of thermal treatment conditions on crystalline structure, lattice parameters, tetragonolity(\%c/a\%) and the relationships of \%a, c, c/a\% with Ca content were discussed. WT5HZ]
Keywords:Calcium modified lead titanate  Nanocrystal materials  Sol\|gel method  Crystalline structure
