Crystallization kinetics and dielectric characterization of CeO2-added BaO–SrO–Nb2O5–B2O3–SiO2 glass-ceramics

Abstract
Abstract Glass-ceramic materials of the SrOBaONb 2 O 5 B 2 O 3 SiO 2 system, with various amounts of CeO 2 added, have been prepared by conventional melt casting followed by controlled crystallization. The effect of CeO 2 addition on crystallization kinetics has been explored for dielectric applications. The addition of CeO 2 to the glass-ceramics decreases the activation energy of crystallization and enhances the dielectric constant as well as breakdown strength remarkably. Glass-ceramic with a dielectric constant of 49, breakdown strength of 1250 kV/mm and energy storage density of 3.39 J/cm 3 could be achieved, so this is promising in high energy storage density dielectrics.
