Abstract

(Ba0.95 Ca0.05)TiO3 ceramic was prepared by solid-state reaction method for different calcination temperatures 1100°C, 1150°C, and 1200°C. X-ray Diffraction (XRD) analysis was performed, it shows that the crystallization starts to form at 1200°C. Sintering was carried out at 1400°C for 3 hours. The sample was characterized by transmission electron microscopy (TEM), scan electron microscopy (SEM), and UV-Visible spectrophotometer. Dielectric properties of this sample were measured in the temperature range 25oC - 140oC, which demonstrates that the maximum dielectric constant (Ɛ) =1982. Rietveld refinement analysis for the XRD pattern is performed, which indicated that Ca-ions enter the tetragonal unit cell and replace Ba-ion and maintain the perovskite tetragonal structure.
