Abstract

Preparation technology and sintering characteristics of the CaO-Al2O3-B2O3-SiO2 system glass ceramics were investigated. Results showed that the glass ceramics of this system could be sintered at 850oC; the material has fine sintering properties, outstanding dielectric properties including low dielectric constant (about 4.85, 1GHz) and low dielectric loss (about 0.1%, 1GHz). XRD analysis indicated that the crystalline phases in the sintered body are mainly Al5(BO3)O6, a trace amount of SiO2 and CaSiO3.
