Newsam, J M; Jorgensen, J D

The syntheses of gallosilicate sodalites from solutions/gels with a range of compositions and their characterization by tga, /sup 29/Si nmr and powder X-ray diffraction are described. Conventional gel compositions generally provide good products albeit typically in low yields. In none of these gel/solution routes are anti-Loewenstein materials with Si:Ga<1.0 observed. Similar to the aluminosilicate system, CAN-framework zeolites can be produced by addition of appropriate anions to the gels/solutions. The structure of a basic gallosilicate sodalite with Si:Ga = 1.25, determined by full profile analyses of time-of-flight powder neutron diffraction data, is essentially similar to that of the analogous aluminosilicates. 24 refs., 3 figs., 5 tabs.
