Abstract: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, mi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
