Abstract

In this study, 94NBT-6BT single crystals were grown by flux growth method using uncalcined and calcined 94NBT-6BT powder. Crystal structures and chemical composition of grown crystals were characterized by X-ray diffraction (XRD), energy dispersive X-ray (EDX) and X-ray fluorescence (XRF) technique. Influences of the powder processing type on dielectric and leakage current properties of the grown single crystals were analyzed by impedance/gain phase analyzer, LCR meter, AIXACT (aixPES/CMA) piezoelectric and ferroelectric analyzer. The results showed that, single crystals which were produced by heat-treated powders gave better dielectric and leakage current properties than uncalcined single crystals.
