Abstract
The densification process, phase shift, microstructure and dielectric properties of CABS/Al 2O 3 system glass-ceramics were studied using DSC, XRD, SEM and EDS. The results show that densification has been achieved at 825°C and dielectric constant (ε r) gets its maximum. At 850°C Anorthite precipitates from the matrix phase, which leads to the significant decrease of dielectric loss (tanδ). With heat-treatment temperatures increasing, tanδ increases slightly due to the loose microstructure. The obtained glass-ceramics at 850°C which have ε r of 7.9 and tanδ less than 1 × 10 -3 can be used as promising LTCC materials.
