Oxygen storage materials which have high surface areas and super oxygen storage property were precipitated by ammonium carbonate, and its' phase, oxygen storage capacity, surface area et al.
This paper about the technics is to use the material of haloid liquid, ammonium bicarbonate and ammonia to preparate the super light MgO.
