摘要：
A temperature stable ceramic dielectric with a low firing temperature (1130-degrees-C) and a high dielectric constant (3700 to 2600) has been developed by sintering the mixture of precalcined lead-based relaxor and prefired modified barium titanate. This dielectric was confirmed to be a two-phase ceramic composite body, according to X-ray diffraction analysis, scanning electron microscopy, transmission electron microscopy and dielectric measurements. A shortcoming of the high dissipation factor in the dielectric has been reduced by incorporating MnO into the barium titanate constituent prior to mixed sintering. This ceramic dielectric meets X7R specifications in the EIA (Electronic Industries Association) standard.
