Abstract:
High purity as well as Ce-, Pr- and Y-doped polycrystalline BaTiO3 ceramics were prepared by wet chemical synthesis. Dielectric constant as well as dielectric loss of dry pressed and sintered ceramics show dielectric constant above 20000 for samples containing 0.5 % Ce accompanied by semiconducting properties. X-ray diffraction studies confirmed Ti being substituted by Ce an Y, while Pr substitutes Ba ions.
