Abstract

Phase purity, microstructure, sinterability and microwave dielectric properties of BaCu(BO)-added LiZnTiO ceramics and their cofireability with Ag electrode were investigated. A small amount of BaCu (BO) can effectively reduce the sintering temperature from 1075°C to 925°C, and it does not induce much degradation of the microwave dielectric properties. Microwave dielectric properties of ε = 23·1, Q × f = 22,732 GHz and τ = − 17·6 ppm/°C were obtained for LiZnTiO ceramic with 1·5 wt% BaCu(BO) sintered at 925°C for 4 h. The LiZnTiO +BCB ceramics can be compatible with Ag electrode, which makes it a promising microwave dielectric material for low-temperature co-fired ceramic technology application.
