摘要：

The effects of Li2O-MgO-B2O3 (LMB) glass additive on the sintering characteristics, phase purity, microstructure, and microwave dielectric properties of Li2MgTi3O8 ceramics were investigated. The experimental results demonstrate that the addition of LMB glass effectively lowers the sintering temperature of Li2MgTi3O8 ceramic from 1025 degrees C to 875 degrees C and induces no obvious degradation of the microwave dielectric properties. Typically, the 1.5% LMB glass-added Li2MgTi3O8 ceramic sintered at 875 degrees C for 4 h shows excellent microwave dielectric properties of Qxf=45403 GHz, epsilon(r)=25.9 and tau(f)approximate to 0 degrees C-1. The dielectric ceramic exhibits stability against the reaction with the Ag electrode, which indicates that the ceramics could be applied in multilayer microwave devices requiring low firing temperatures.
