| Abstract | Ultrafine-grained ceramics based on nano-scale barium titanate for BME-MLCC applications have been prepared. Relationships of milling time, microstructures and dielectric properties have been investigated. With processing selected carefully, the present ceramics show ultrafine grain size (180nm) and homogeneous microstructures, well with high dielectric constant (ε25=2550), low dielectric loss (<0.02), high resistivity, high breakdown field and X7R temperature specifications, which would be promising materials for the next generation BME-MLCC applications. |
