Abstract or Summary
  • 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 constant, decreasing the BaTiO[subscript 3] content leads to a broadening of the temperature-dependent permittivity maximum and a decrease in the overall permittivity. For compositions of constant BaTiO[subscript 3] content, replacing Bi(Zn[subscript 1/2]Ti[subscript 1/2])O[subscript 3] with NaNbO[subscript 3] shifts the temperature of the maximum permittivity to lower temperatures (e.g., to -103 A degrees C for a composition of 70BT-5BZT-25NN) while maintaining a broad permittivity peak with temperature, which for the 50BT-25BZT-25NN composition also satisfies the X9R standard. Thus, the investigation of BT-BZT-NN compounds resulted in promising dielectric properties with broad temperature ranges of high permittivity, which is of interest for advanced capacitor applications.
