X-Ray Diffraction and Dielectric Constant of Lanthanum Doped Barium Titanate Ceramics

Abstract:

Undoped barium titanate and lanthanum (La) doped barium titanate (BaTiO₃) were studied for ferroelectric properties with the formula of Ba_1-_xLa_xTi_1-_x_/4O₃ for x=0.1 and being prepared by using conventional solid state method reaction. The pure phase of this composition which x=0 were found at final heating temperatures starting from 1300°C and x=0.1 at 1350°C for overnight in air with intermittent grinding. The changes in the crystal structure of the composition were detected by using X-ray diffraction. Impedance Spectroscopy analysis is carried out to determine the dielectric properties for undoped BaTiO₃ and La doped BaTiO₃ for x=0.1.
