由BaNd2Ti5O14陶瓷和无铅稀土硼玻璃(LBT)合成的玻璃陶瓷复合材料可以用于制备低温共烧陶瓷元器件(LTCC).本研究对这种玻璃陶瓷复合材料进行了检测,并分析探讨了它的相对密度、收缩率和微波介电特性(εr,Q×f0).低温烧结体呈现出可应用的特性,即:相对密度高,超过85%,介电常数εr为13～20,Q×f0为2000～10000.结果显示,这种复合材料在制备高频低温共烧陶瓷元器件方面有很好的应用前景.“,”For Iow temperature co-fired ceramics (LTCC) materials, a glass-ceramic composite consisting of a BaNd2Ti5O14ceramic, and a lead-free rare earth derived boron glasses (LBT) was tested in this present study. The glass-ceramic composite was evaluated for relative densities, shrinkage and microwave dielectric properties (εr, Q×f0). The sintered body at low temperature demonstrated applicable properties such as high relative density over 85% and various dielectric properties,namely 13～20 for εr, 2000～10000 GHz for Qxf0. The results suggest that the composite has a good potential for using low temperature co-fired ceramic compositions for high-frequency application.
