Addition of an optimal amount of the BaO-B2O3-SiO2 glass to BaTiO3 compacts accelerated densification with a limited grain growth. The sintering temperature of the BaTiO3 ceramics was lowered to 900 degrees C with high density above 93%. Furthermore, there was no formation of secondary phases in the sintered bodies at the optimal amount of the glass. Higher dielectric constant was obtained from the BaTiO3 ceramics with I wt% BaO-B2O3-SiO2 glass, sintered at 900 degrees C, than those observed for the pure BaTiO3 sintered at 1350 degrees C.
