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 Pb1-xCaxTiO3 powders. The lattice parameters and c/a ratios were determined by using XRDmethod. The grain sizes of powders were detected by TEM photographs and X-ray diffraction. The influence of thermal treatment conditions on crys-talline structure, lattice parameters, tetragonolity(c/a) and the relationships of a, c, c/a with Ca content were discussed.

Key words: Calcium modified lead titanate, Nanocrystal materials, Sol-gel method, Crys-talline structure
