Abstract:Sr0.6Ba0.4Nb2O6 micro-rods are prepared by the molten-salt method with K2SO4, KCl-K2SO4, and KCl as fluxes. It reveals that the Sr0.6Ba0.4Nb2O6 synthesized with KCl as a flux exhibits a single phase with tetragonal tungsten bronze structure. The measurement of X-ray diffraction indicates that the Sr0.6Ba0.4Nb2O6 micro-rods synthesized at 1 300℃ are anisotropic. The morphology of the powers is examined by transmission electron microscope. It reveals that the length-diameter ratio of Sr0.6Ba0.4Nb2O6 micro-rods increases with increasing annealing temperature from 900℃ to 1 300℃. At 1 300℃, the rod possesses a large length-diameter ratio of 8: 1. Moreover, the analysis of the piezoelectric properties of single micro-rods using a piezo-response force microscope indicates that the domains of the material are arranged along its radial direction. © 2018, Editorial Department of Transactions of NUAA.
