Electrical and physical properties of modified potassium sodium niobate ceramics prepared by molten salt synthesis
In the present work, molten salt method was applied to synthesize the 0.9875(K 0.5 Na 0.5 )NbO 3 -0.0125BiScO 3 (KNN-BS) powders. Pure phase of KNN-BS powder was obtained for a calcination temperature of 700°C which lower than a conventional mixed oxide method by 250°C. The KNN-BS ceramics were fabr...

| Summary: | In the present work, molten salt method was applied to synthesize the 0.9875(K 0.5 Na 0.5 )NbO 3 -0.0125BiScO 3 (KNN-BS) powders. Pure phase of KNN-BS powder was obtained for a calcination temperature of 700°C which lower than a conventional mixed oxide method by 250°C. The KNN-BS ceramics were fabricated by a solid-state reaction technique. Effects of excess Na and K on the properties of the ceramics were investigated. The excess Na and K produced an increase in dielectric constant at the ferroelectric to paraelectric transition temperature as well as change the transition temperatures. Further, the ferroelectric behavior was also improved by the additives. © 2013 Copyright Taylor and Francis Group, LLC. |
