Abstract
- Abstract: The influence of Nb on the microstructure and dielectric properties, including temperature dependence of permittivity, dielectric loss, and Curie temperature, has been investigated on Ni-doped BaTiO3 ceramics. Experiments reveal that incorporation of a proper content of Nb in Ni-doped BaTiO3 can control the grain growth, reduce the dielectric loss, shift the Curie temperature to higher temperatures and significantly improve temperature characteristics of the BaTiO3 ceramics. As a result, a novel X8R material is developed in the system, which is very promising for practical use in X8R multi-layer ceramic capacitors (MLCCs). [Copyright &y& Elsevier]
