The nickel and ammonia solution contains 22 ratio of nickel to ammonia (molar), which is roughly 50 grams nickel per liter of solution. The nickel-ammonia solution is then reduced with hydrogen in autoclaves, adding a a small amount of ferrous ammonium sulphate. This solution is heated to 250 deg F at 350 PSI, in a hydrogen atmosphere.
