SrO–BaO–Nb2O5–B2O3system glass-ceramics with Gd2O3/BaF2addition have been prepared by controlled crystallization method. The effect of Gd2O3/BaF2addition on the phase evolution, dielectric properties and energy storage properties has been investigated. The addition of Gd2O3/BaF2to the glass-ceramics changes the dielectric property and energy storage density. The glass-ceramics with 0.5 mol% Gd2O3and 4.5mol% BaF2heat treated at 850°C/3h possesses a dielectric constant of 125, a breakdown strength of 1055 kV/mm and energy storage density of 6.16J/cm3, which are promising materials for high energy storage density dielectrics.

Storage Properties

Sr0.5Ba0.5Nb2O6 (SBN) ceramics with the BaO–B2O3–SiO2 (BBS) glasses have been successfully produced for high energy-storage density capacitor applications. The phase evolution, microstructures, dielectric properties and energy storage properties of the SBN-based glass ceramics were investigated. X-ray diffraction analysis revealed all ceramic samples were of tetragonal tungsten bronze-type structures. As the mass ratio of glass in the glass ceramics increased from 0.1wt.% to 10 wt.%, the dielectric constant of the glass ceramics increased initially and then decreased with the increasing glass content. Compared to pure Sr0.5Ba0.5Nb2O6 ceramics, the glass ceramics with a small amount of BBS glass addition illustrated better energy storage properties. The glass-ceramic with 0.5wt. % BBS glass addition showed the highest breakdown strength of 194 kV/cm and a maximum energy storage density of 0.286 J/cm3.
