ABSTRACT:
Method for processing an article comprising a mixed conducting metal oxide material, which method comprises (a) contacting the article with an oxygen-containing gas and reducing or increasing the temperature of the oxygen-containing gas; (b) when the temperature of the oxygen-containing gas is reduced, reducing the oxygen activity in the oxygen-containing gas; and (c) when the temperature of the oxygen-containing gas is increased, increasing the oxygen activity in the oxygen-containing gas.
