Lead lanthanum zirconate titanate stannate (PLZST) single crystals have been successfully grown by a flux method using KF as flux. Well-developed single crystals with sizes of 2.0 min x 2.0 mm x 1.5 mm were obtained for the first time. The crystal morphology was studied and related to a layer growth mechanism controlled by two-dimensional growth. Crystal structure measured by X-ray diffraction technique was single perovskite. The chemical composition of as-grown crystal was analyzed by an energy dispersive X-ray spectrometer and inductively coupled plasma atomic emission spectrometry. The maximum dielectric constant was determined to be 2400. The Curie temperature was found to be about 170 degrees C, similar to the polycrystalline data. (c) 2005 Elsevier B.V. All rights reserved.
