Synthesis,Structure and Properties of BaZrxTi1-xO3·yLa2O3 Solid Solutions

Abstract

Abstract: Aseries of BaZr_xTi_1-xO₃·yLa₂O₃(0≤ x ≤0.3, 0≤ y ≤0.04) solid solutions were synthesized by means of soft chemical method at 95 ℃. XRDand d-spacing-component figures of the series of the solid solutions proved that the compounds are mutual miscible in the solid solutions. Further, through a TEM, the product is found to have a shape of uniform, substantially spherical particles with an average particle diameter of 60 nm. The result of preparing ceramics showed that adulterating with zirconium and lanthanum in pure BaTiO₃ phase obviously improved the dielectric constant at normal temperature.

Key words: BaTiO₃ solid solution, Synthesis, Dielectric character
