Abstract:

        In the present investigation, the electrophoretic deposition of Ca-modified PbTiO3 (abbreviated to PCT) films has been attempted. The preparative parameters are optimized forelectrophoretic deposition of the films. Pb1-xCaxTiO3 ceramic thin films are prepared from theraw materials of PbO, CaO and TiO2 with purity of 99.9%. By changing the Ca content(1-4 mol%) and heating temperatures 200˚C and 500˚C, the influence of variousprocessing parameters on the ferroelectric and pyroelectric characteristics of PCT samples are studied. The results are discussed at length in this paper,
