## Description

- description: "<sup>23</sup>Na NMR spectra of Na-K form low silica X zeolite loaded
    with potassium for saturating level, which corresponds to 9.0 atoms per unit,
    have been observed. Other than a centered grain of the spectral component, another
    separated peak component with shift of somewhat larger than bulk Na has been detected.
    Such the extra peak component shows complex hysteresis on temperature and is accompanied
    with quite slow dynamics of days-order. It is attributed to atomic re-configurations
    among sites occurs in the course of melting and re-crystallization process among
    alloy of sodium and potassium, which possibly is formed on surface or outside
    of the zeolite crystals."
