A Study of the Mixed Na1-xLix Zeolite A System by Powder X-ray Diffraction, J.M. Newsam, R.H. Jarman and A.J. Jacobson, J. Solid State Chem., 58, 325 (1985).
A simple analysis of the ratios of selected X-ray powder diffraction intensities from anhydrous sodiumlithium zeolite A samples, Na12−xLixSi12 Al12O48, shows that Li replaces Na in site I for 0 ≤ x ≤ 8. This result is discussed in relation to previously reported 29Si NMR data and a model is presented for the cation ordering scheme in the anhydrous mixed material with x = 4. Changes in the X-ray pattern with external water vapor pressure are also described.
