Microwave Dielectric

The effect of different amount of LMZBS glass on the sintering behavior, microstructure and microwave dielectric properties of the Li2(Mg0.96Ni0.04)SiO4 ceramics was investigated. The synthesis of materials was based on the solid-state reaction method. The micromorphology of the composite ceramics was confirmed using scanning electron microscopy. The microwave dielectric parameters were measured by the network analyzer. The mechanism of heat transfer coming from LMZBS glass lower the densification temperature of matrix ceramic from 1150°C down to 900°C. Excellent microwave dielectric properties were obtained with 1.2 wt% LMZBS glass sintered at 900°C for 4h (εr=5.77 and Q×f=29,558 GHz at 16 GHz, τf=-14.5 ppm/°C). There was a compatibility between the composite ceramic and Ag. Therefore, the aimed ceramic has great potential value of application in the field of low temperature co-fired ceramics of millimeter-wave devices.
