抄録

Densification behavior and micro structural characteristics were examined for BaTiO₃ containing 0.25-2.00mass% Li₂Si₂O₅. Li₂Si₂O₅ lowered the sintering temperature of BaTiO₃. The optimum concentration to obtain high density was 1mass%. A concentration smaller than the optimum value did not effectively lower the sintering temperature, while a larger concentration resulted in the formation of inhomogeneous microstructure. There was an optimum sintering temperature to obtain compacts with maximum density. Extensive grain growth occurred above the optimum temperature. The grain boundary phase, which was a liquid phase at the sintering temperature, contained TiO₂-rich particles, whose distribution was non-uniform. The formation mechanisms of such microstructure were discussed.
