摘要

This study investigated the impact of SrCoO3 (SCO) addition on the dielectric properties of BaTiO3 ceramics sintered under reducing atmospheres, targeting applications in base metal electrode multilayer ceramic capacitors (BME MLCCs). The objective is to develop materials meeting stringent requirements for high dielectric constant, low loss, and compliance with X8R specifications. Results indicate that doping with 0.05 wt% SCO significantly enhanced MLCC performance, achieving temperature coefficient of capacitance (TCC) values compliant with X8R specifications. This optimal doping concentration enhanced room temperature resistivity, reduced leakage current, and improved impedance characteristics. These improvements stem from an effective reduction in oxygen vacancy content and Ti3+ ion proportion. The findings suggest that BaTiO3-based ceramics doped with 0.05 wt% SCO fulfill the demanding criteria of high-performance BME MLCCs, promising heightened dielectric properties, reduced losses, and enhanced temperature stability and reliability.
