ABSTRACT:
A complex oxidation reaction product of two or more metals in an oxidized state is formed by positioning a suitable precursor metal adjacent to a permeable mass of a metal-containing compound in an oxidizing atmosphere and heating the assembly to form a body of molten precursor metal. The molten metal infiltrates the permeable mass and reacts therewith and with the oxidizing atmosphere to form a complex oxidation reaction product. Methods for determining the shape of the resulting article are described. The disclosed methods can be used to form superconducting perovskites.
