Summary:Barium–calcium–aluminum–borosilicate glass is added as a sintering promoter to reduce the sintering temperature of barium titanate. The dielectric properties of the glass-added barium titanate-based internal capacitors are investigated. The dielectric constants of the composites were found to increase with sintering temperature. A capacitance of about 2.3 nF/cm 2 with the dissipation factor of 2.9% is obtained for a 20 wt% glass-added BaTiO 3 internal capacitor after being cofired with low dielectric constant ceramic substrate at 950°C. The percent change of capacitance is confined within ±10% and the dissipation factor is stable in the measured temperature range.
