The Al content of mordenite frameworks can be estimated without calcul
ating the unit cell constants. The number of Al atoms in the framework
of mordenites can be related to the spacing between two peaks (402) a
nd (004) by a linear equation. The framework composition of mordenites
can be also determined from the peak intensities of the (200) and (15
0) reflections.
