Popis:	Using X-ray powder diffraction, the structure and distribution of the exchangeable cations of dehydrated Na{sub x}HGaY (x = 54, 36,and 21) was determined and compared to Na in dehydrated (Al)Y. From this, it is concluded that the substitution of Al by Ga results in a less polarizable and more ionic framework. 24 refs., 5 figs., 6 tabs.
