The defect mechanisms that underpin the high energy density dielectric 0.8BaTiO₃–0.2Bi(Zn₁/₂Ti₁/₂) O₃
were investigated. Characterization of the nominally stoichiometric composition revealed the
presence of a Ti³⁺-related defect center, which is correlated with lower resistivities and an
electrically heterogeneous microstructure. In compositions with 2 mol. % Ba-deficiency, a barium

Dielectric ceramics designed for capacitor applications for use in extreme environments, such as high temperatures, high voltages, or high-pressure environments, are in great demand. Existing capacitor technology fails to perform within these extreme conditions or such environments. The development of new dielectric ceramic materials for high temperature capacitor applications is...
In order to develop dielectric ceramics with temperature-stable permittivity characteristics, perovskite BaTiO[subscript 3]-Bi(Zn[subscript 1/2]Ti[subscript 1/2])O-[subscript 3]-NaNbO[subscript 3] ceramic solid solutions were investigated with a particular focus on effects of BaTiO[subscript 3] and NaNbO[subscript 3] contents on the dielectric properties of ternary compounds. Keeping the ratios of the other two constituents...
