Open the CIPO recordAbstract From the Canadian patent
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 articles (e.g. superconducting perovskites.)

Why it's free to use
- Granted May 25, 1993. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended May 25, 2010.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
