Sintering, Microstructure and Dielectric Properties of Ca-Al-B-Si-O Glass/Al₂O₃ Composites with Various SiO₂ Content

Abstract:

The effects of silicon dioxide addition on the sintering, microstructure and microwave dielectric properties of Ca-Al-B-Si-O glass/Al₂O₃ composites were investigated. Results show that: Increasing the silicon dioxide content in the glass leads to the corresponding rise of bulk density, dielectric constant of the LTCC materials and the decrease of its dielectric loss and porosity. A bulk density of 2.92 g·cm^-3, a porosity of 0.2%, aε_r value of 7.11 and a tan δ value of 0.00096(measured at 10 MHz) are obtained for 68 wt% silicon dioxide of the samples sintered at 875°C for 30 min.
