Preparation and Characterization of Sodium Tantalate Thin Films by Hydrothermal−Electrochemical Synthesis
Source abstract
Abstract
Crystalline sodium tantalate thin films with pyrochlore (Na 2 Ta 2 O 6 ) and perovskite (NaTaO 3 ) structures are successfully synthesized on Ta metal substrates by a hydrothermal−electrochemical method at low temperature (≤473 K). The phase, film thickness, and domain size of the synthesized films are shown to be controllable by appropriate adjustment of the reaction conditions. Film formation mechanisms for both Na 2 Ta 2 O 6 and NaTaO 3 are proposed based on the experimental results.
