The purpose of present study is to sinter BaTiO<SUB>3</SUB> ceramics at lower temperature than the conventional one. The lower temperature sintering was performed by adding lead boro-silicate glass to BaTiO<SUB>3</SUB>, and dielectric properties were evaluated for every content of the glass (0.3. 0.6 and 1.2 mol%). The effects of the glass are more significant in the lower sintering temperature such as 1273K. In particular, 1.2 mol% addition of the glass enhanced a relative permittivity which was 1600 at 1 KHz and a dielectric loss up to 1 MHz were not inferior to those of specimens sintered at 1473 K. The dielectric loss was about 3 % at the frequencies more than 10 kHz. The effects of a glass are discussed with the model for the two phases such as BaTiO<SUB>3</SUB>, and grains or pore by the equivalent curcuit.
