Barium titanate, BaTiO₃ (BT) and Barium calcium titanate zirconate BaCa(Ti Zr)O₃ (BCTZ) ceramics were prepared by dry pressing. The prepared ceramic bodies were sintered at different temperatures, 1100, 1150 and 1200°C/4h., physical properties in terms of bulk density as well as relative density and average grain size were studied. Phase composition using X-ray diffraction (XRD) was investigated to these ceramic bodies at the previous temperatures, Microstructure using scanning electron microscopy (SEM) was studied to the selected samples at 1200°C/3h. It was found that the pure perovskite of (Tetragonal-orthorhombic) (BT) and (Cubic-orthorhombic) (BCTZ) ceramics was obtained at 1200 °C/4h. Prepared bodies BT and BCTZ, sintered at 1200 °C/4h have uniform very fine grain size porous microstructure, with average grain size 604, 804 nm as well as relative density recorded 83.26, 92.39%, respectively. Dielectric constant (ε) enhanced and recorded, 2802.25 for BCTZ and 27.59 for BT ceramics
