Storage Properties

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 Density

The influences of BaF2 addition on phase composition, electrical property and energy storage density in strontium barium niobate based glass-ceramics prepared using melt-casting followed by controlled crystallization were investigated. The results indicate that adding 1wt% BaF2 improves the precipitation of Ba0.27Sr0.75Nb2O6 phase. However, the secondary phases, Ba3SrNb2O9 and BaBF5 are formed as the amount of BaF2 exceeds 3wt% when heated at 800°C/3h+900°C/3h in the glass-ceramics. The dielectric constant, microstructure, volume resistivity and breakdown strength are related to BaF2 content. The maximum breakdown strength (1450 kV/cm) and the energy storage density (5.1J/cm3) can be obtained in the glass-ceramic sample with 1wt% BaF2 addition, which would be suitable to be used as the dielectric materials for high energy storage capacitors.
