Abstract

There is disclosed a method of forming crystalline tantalum pentoxide on a ruthenium-containing material having an oxygen-containing surface wherein the oxygen-containing surface is contacted with a treating composition, such as water, to remove at least some oxygen. Crystalline tantalum pentoxide is formed on at least a portion of the surface having reduced oxygen content.
