Surface reactor is made from an alloy of 90-95% tin, 3-5% copper, 0.05-0.2% silver and 0.001-0.01% gold. The material is cast in a mold and cut, so that the cut material can be deformed and has a strip thickness of 0.1-0.5 mm. Independent claims are also included for; (1) A process for activating the surface reactor; and (2) A process for recovering a liquid propellant additive by filtering an activated sludge in a fine filter, and purifying with alcohol. |
