Abstract

A natural leucite sample, its Rb- and Cs-exchanged derivatives, and analcime, have been examined using ²⁹Si and ²⁷Al MAS NMR spectroscopy, with the objective of providing a better understanding of the Si-Al distribution in these phases. Spectra were obtained at temperatures from 25 to 600°C for leucite and from 25 to 200°C for the Cs-exchanged leucite through its tetragonal-to-cubic structural phase transition. The short-range Si-Al order was also investigated for several samples of the structurally related mineral analcime. -from Authors
