Research Trends on the Influence of Oxygen Vacancies in Post BaTiO3 (BT) Ceramics for Next-Generation MLCCs

In line with the trend towards electrification in mobility, there is a demand for development of next-generation Multilayer Ceramic Capacitors(MLCCs) superior properties compared to those using conventional BaTiO<sub>3</sub> (BT) ceramics. For this, various high-performing ferroelectric ceramics have been proposed as post-BT materials, and numerous studies conducted on role oxygen vacancies within these materials. It has confirmed that ceramic material significant impact such ionic conduction, IR degradation, microstructure, aging hardening effect, by controlling concentration mobility vacancies, it possible adjust properties. We hope research will be utilized foundation knowledge MLCCs future.
