8Y-Stabilized Cubic Zirconia Addition Effect on Barium Titanate

The addition effect of 8Y- stabilized cubic zirconia (8YSZ) on Barium Titanate (BaTiO3) with molar ratios of x = 0.025, 0.05, 0.1 was studded using the mixed solid oxides method. The preparation was completed by high temperature solid state reaction at a sintering temperature of 1300C, 1350C and 1370C. X- ray diffraction (XRD) measurements confirmed the presence of single-phase perovskite like structure for the sintered samples. The microstructure observations by scanning electron microscopy (SEM) revealed the sensitivity of the grain growth with the heating schedul of sintering. The electrical conductivity of the different samples had been elucidated by ac measurements as a function of temperature. The dielectric results show high increase of the dielectric constant with some decrease of the curie temperature.
