Correlation between dielectric breakdown strength and interface polarization in barium strontium titanate glass ceramics

The correlation between the dielectric breakdown performance and interface polarization was studied by the measurements of the dielectric breakdown strength and impedance spectroscopy as a function of sintering temperatures in a BaO - SrO - TiO 2 - Al 2 O 3 - SiO 2 glass ceramic system. It was found...

Description
Summary:The correlation between the dielectric breakdown performance and interface polarization was studied by the measurements of the dielectric breakdown strength and impedance spectroscopy as a function of sintering temperatures in a BaO - SrO - TiO 2 - Al 2 O 3 - SiO 2 glass ceramic system. It was found that dielectric breakdown strength strongly depends on the interface polarization. The sintering temperature dependence of breakdown strength is attributed to the variation in interfacial polarization based on the results of complex impedance analysis.
