N2 - It is critical to find an appropriate sintering aid to reduce the sintering temperature of the temperature compensated (Ca,Sr)(Zr,Ti)O3 (CSZT) ceramics while manufacturing multilayer ceramic capacitors (MLCCs) with copper electrodes. The effects of the addition of lithium borosilicate glass on the microstructure and dielectric properties of (Ca0.7Sr0.3) (Zr0.97Ti0.03) O3 sintered in a reducing atmosphere have been reported. However, the relationships between the defect chemistry and the dielectric properties of Li-B-Si based glass added to CSZT ceramics have not been clarified. This study investigated the Li-B-Si-Ca-Mn (LBSCM) glass addition effects on the dielectric relaxation and AC impedance of sintered CSZT ceramics sintered in a reducing atmosphere based on the defect chemistry. It was observed that the dielectric relaxation peaks and AC impedance are intimately related to the defect associates Vo··-Lizr′. The CSZT ceramics added with LBSCM glass can be densified at temperatures below 1000 °C and have lower dielectric losses, making them a promising choice for use as a dielectric ceramic in copper electrodes MLCCs.
