Claims
- 1. A process for producing an improved calcium chemical pump, comprising reacting calcium and anhydrous ammonia in an evacuated vessel that is cooled to a temperature between 0.degree. C. and -30.degree. C. to form a solution of the calcium and anhydrous ammonia, spraying said solution onto a porous foamed substrate material that is being rotated in a closed container that is being maintained at about room temperature, and maintaining a vacuum in said closed container as said solution is being sprayed into said closed container and onto said substrate material to cause ammonia to be drawn off by said vacuum and calcium to be deposited throughout the porous foamed substrate material as said substrate material is being rotated.
- 2. A process for producing an improved calcium chemical pump as set forth in claim 1, wherein an inert gas is introduced into said closed container after said calcium has been deposited to pressurize said closed container.
- 3. A process for producing an improved calcium chemical pump as set forth in claim 1, wherein said substrate material is selected from the group consisting of copper, nickel and alumina and said substrate material has a porosity of between 70 and 95 percent.
- 4. A process for producing an improved calcium chemical pump as set forth in claim 3, wherein said substrate material has a porosity of about 90 percent.
