Effect of Rapid Sintering on the Core-Shell Microstructure and Reliability for Ni-BaTiO3 Multilayer Capacitor

Abstract

Microstructural control is important to obtain the good reliability in thin-layer multilayer ceramic capacitors. This research aims to investigate the possibility for further improvement of microstructure and reliability on Ni- BaTiO3 multilayer capacitors via the kinetic approach. It indicates that the rapid sintering increases the ratio of core-shell grain, and the excellent reliability is obtained. Simultaneously, rapid sintering also significantly increases the continuity of nickel electrodes to obtain a high capacitive volumetric efficiency in high-capacitance multilayer capacitor.
