Patent ID: 7510995

Claim:
A method for applying a mixed metal oxide catalyst system to a metallic substrate to form a high-temperature catalyst for use in the decomposition of hydrogen peroxide or other propellant comprising: providing a prepared metallic substrate; forming a high-activity catalyst composition, wherein said high-activity catalyst composition comprising between about 10 to 20 weight percent of alumina and being selected from the group consisting of a Type I catalyst composition and a Type II catalyst composition; combining an organic solvent with said high-activity catalyst composition to form a catalyst slurry, said organic solvent being volatile under gentle heating; applying a layer of said catalyst slurry to said prepared metallic substrate; drying said catalyst slurry applied on said prepared metallic substrate to form a layer of a catalyst material on said prepared substrate to form a catalyst coated prepared substrate; binding said layer of said catalyst material to said prepared metallic substrate thus forming a binded layer on said prepared substrate; applying an activation treatment to said binded layer; and calcining said activation treatment to said binded layer.
