抜粋

Crystalline sodium tantalate thin films with pyrochlore (Na 2Ta2O6) and perovskite (NaTaO3) 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 Na2Ta2O6 and NaTaO3 are proposed based on the experimental results.
