Abstract

Plate-like sodium niobate (NaNbO3) particles with a high aspect ratio are synthesized via a two-step topochemical method. The Aurivillius phase Bi2.5Na3.5Nb5O18 (BNN5) is prepared in NaCl flux as precursor for templated grain growth (TGG) of NaNbO3 crystals. The preferred orientation along the (00l) crystal planes is retained in the topochemical conversion process by substituting Bi3+ in the [Bi2O2]2+ layers. Consequently, highly orientated NaNbO3 crystals with lengths of 7-18 μm and thicknesses of 1-3 μm are obtained under various conditions, providing suitable templates for textured ceramics and composite devices for piezoelectric actuators or energy harvesters.
