The exchangeable and non-exchangeable Na in tetrasilicic sodium fluor mica (Na-TSM) are characterized by different chemical shifts both in XPS and NMR. The exchangeable Na shows Na is binding energy (Na KLL kinetic energy) comparable to that for montmorillonite or analcite. The non-exchangeable Na has the characteristic low Na is binding energy (high KLL kinetic energy) and positive 23Na NMR chemical shift. NMR spectra suggest the higher coordination symmetry and the shorter bonding with ligand for the non-exchangeable Na.
