The oxide framework is negatively charged and possesses very small cavities. Metal cations are present within the cavities to make the solid neutral. The ionic nature of the solid creates an electric field within the cavities. This electric field gradient is enhanced if divalent ions such as Ca2+ instead of Na+ are the charge balancing counter ions. When gas molecules get inside the tiny pores, they interact strongly with the wall of the pores. Having different electronic configuration, nitrogen and oxygen interact with the wall differently, with nitrogen bound more tightly inside the cavities. By pressuring air in contact with the zeolite, nitrogen is separated from oxygen by preferential adsorption within the pores of the zeolite. Gas stream with 95% oxygen > 99% nitrogen can be produced. \(and~now~you~know~the~Secret~too~!!~Nice~to~meet~You~!\)
