Abstract:  For low temperature co-fired ceramics (LTCC) materials, a glass-ceramic composite consisting of a BaNdTigO.4 ceramic, 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, Qxf₀). The sintered body at low temperature demonstrated aplicable properties such as high relative density over 85% and various dielectric properties,namely 13~20 for er, 2000~10000 GHz for Qxf₀The results suggest that the composite has a good potential for using lowtemperature co-lired ceramic compositions for high-frequency application.
