Dielectric Breakdown Strength of Grain-Oriented Bi4Ti3O12Ceramics

摘要: DC dielectric breakdown strength Eb of grain-oriented Bi4Ti3O12 ceramics fabricated by the hot-forging method and cold-uniaxial pressing has been studied. In sample with X-ray orientation factor 0.84, was about 22 MV/m, when electric field applied parallel to axis ceramics. On other hand, 16 perpendicular axis. It found that grain is effective in increasing
