Improved discharged property for (BaO, Na2O)–Nb2O5–SiO2 glass-ceramics by La2O3 addition
Source abstract
Abstract
Abstract The (BaO, Na 2 O)–Nb 2 O 5 –SiO 2 glass-ceramics with various amounts of La 2 O 3 addition, were fabricated through melt casting followed by controlled crystallization. The effect of La 2 O 3 addition on the phase transition, microstructure, and dielectric properties for (BaO, Na 2 O)–Nb 2 O 5 –SiO 2 glass-ceramics was investigated. With the addition of La 2 O 3 , the dielectric constant and the breakdown strength for the glass-ceramics were drastically improved, which resulted in the improvement of the discharged property. The maximum energy-storage density of 8.4 J/cm 3 was achieved in the niobate glass-ceramics with 0.5% La 2 O 3 addition, indicating that the glass-ceramic with this composition is a promising dielectric material for high energy storage density capacitors.
