摘要: Nano BaTiO3-based dielectric ceramics were prepared by chemical coating approach, which are promising for ultrathin multilayer ceramic capacitor (MLCC) applications. The doping effects of Mn element on the microstructures and properties investigated. degradation test impedance spectroscopy employed to study resistance conduction mechanism Mn-doped nano-BaTiO3 samples. It has been found that reliability characteristics greatly depended content. Moreover, BaTiO3 with grain size in nanoscale is more sensitive content than sub-micron scale. addition 0.3 mol. % beneficial improving nano ceramics, an important parameter MLCC However, further increasing amount will deteriorate performance
