Abstract Aseries of sealing glasses with low dielectric constant (3.92≤εr≤4.11), low dielectric loss (5×10-4≤tanδ≤12×10-4) were successfully synthesized by high temperature melt method under SiO2-B2O3-Al2O3-R2O. The synthesized sealing glasses were characterized by infrared spectroscopy (FTIR), Raman spectroscopy, expansion coefficient tester, bending beam high temperature viscometer, and precision impedance analyzer. In addtion, the influence on the performance of the sealing glasses were investigated for SiO2/B2O3 mass ratio. The result showed that the thermal expansion coefficient and dielectric loss of the sample decrease first and then increase with the increase of SiO2/B2O3 mass ratio, whereas the characteristic temperature increases first and then decreases with the increase of SiO2/B2O3 mass ratio. The dielectric constant of the sample increases with the increase of SiO2/B2O3 mass ratio.
