Abstract : A process is described for producing a calcium chemical pump which includes reacting calcium and anhydrous ammonia in a closed vessel that is cooled to a temperature below 0 C to form a solution of the calcium and anhydrous ammonia and then spraying the solution onto a rotating porous foamed substrate material in a closed container that has a vacuum pulled thereon, and the solution when sprayed causing the ammonia to flash and be evaporated and drawn off by the vacuum to cause the calcium to be deposited on the rotating porous foamed substrate material.
