The ceramic of (0,2)BaTiO3–(0,8)BaZr0.5Ti0.5O3 (BT-BZT) system has been manufactured to meet the specifications of the Multilayer Ceramic Capacitor (MLCC). This study aims to determine the effect of annealing temperature on the optical properties, crystal structure, morphological structure, and dielectric properties of BT-BZT materials using X-Ray Diffraction (XRD) characterization, Uv-Vis, F…
