Dielectric property and energy storage performance enhancement for iron niobium based tungsten bronze ceramic

“…As one of the most widely distributed metal elements in nature with unique inherent character, iron is broadly involved in the research of electronic materials and the related compounds show unique magnetic, microwave absorbing and optical properties. [24][25][26][27][28][29] In perovskites, BiFeO 3 -based ceramics show considerable potential in energy storage applications, the large leakage current and lower E b induced by the reduction of Fe 3+ (Fe 3+ + e − / Fe 2+ ) can be greatly improved by chemical doping with a rare earth cation (such as La 3+ ), alkaline earth metal cation (such as Na + and Sr 2+ ) and transition metal cation (such as Nb 5+ ). [30][31][32][33] However, few studies have paid attention to the effect of Fe substitution on polarization, E b and energy storage property for tungsten bronzes.…”
