The addition effects of ZnO-B2O3-SiO2 (ZBS) glass on both the sintering behavior and dielectric properties of BaTiO3 were investigated in developing low-temperature-fired BaTiO3-based ceramics for LTCC devices. X-ray diffractometer (XRD), scanning electron microscopy (SEM), and a dilatometer were used to examine the effect of ZBS glass on BaTiO3 densification and the chemical reaction between the glass and BaTiO3. The results indicate that ZBS glass can be used as a sintering aid to reduce the sintering temperature of BaTiO3 from 1300 to 900 °C without secondary phase formation. The dielectric properties of BaTiO3 with ZBS glass sintered at 900 °C show a relative density of 95%, a high dielectric constant of 994, and a dielectric loss of 1.6%.
