Preparation and Electrical Behaviour of BaCeO₃ Ceramics

Abstract:

Barium cerate (BaCeO₃) ceramics were synthesized via a solid-state reaction technique. Pure phase perovskite powders were obtained at a calcination temperature of 1200 °C. BaCeO₃ ceramics were fabricated from the calcined powder and their properties were investigated. XRD data of the ceramics was consistent with an orthorhombic symmetry. However, the pure phase perovskite of the BaCeO₃ ceramics was only observed for sintering temperatures less than 1500°C. The microstructural analysis indicated that grain sizes of the ceramics increased with increasing sintering temperature. The dielectric constant of the samples had a constant value over a very wide range of temperature. All ceramics showed very good dielectric performance where the ceramics sintered at 1450 °C showed the highest dielectric constant.
