Iv. Mishin et al., APPLICATION OF X-RAY-DIFFRACTOMETRY IN DETERMINING THE COMPOSITION OFTHE MORDENITE FRAMEWORK, Kinetics and catalysis, 34(1), 1993, pp. 174-182
On the basis of x-ray diffraction data and Si-29 NMR spectra, linear r
elationships have been found between the elementary cell constants of
NH4 and H mordenites and the number of aluminum atoms. It is proposed
that an equation relating the Al content to the lattice constants shou
ld be used to determine the composition of the mordenite framework. Ex
amples are given to illustrate the application of this equation in eva
luating the state of aluminum in specimens that have gone through calc
ination and acid treatment.
