摘要：

First time we report the synthesis, structural characterization and thermal behavior of an unusual N-3 (-) containing alumino-silicate sodalite mineral. Azide sodalite, Na-8[AlSiO4](6)(N-3)(2) has been synthesized under hydrothermal conditions at 433 K in steel lined Teflon autoclave. The structural and microstructural properties of azide sodalite mineral was characterized by various methods including FT-IR, XRD, SEM, TGA, and MAS NMR. Crystal structure have been refined by Rietveld method in space group, indicating that the N-3 (-) sodalite has cubic in lattice. High temperature study was carried out to see the effect of thermal expansion on cell dimension (a (o)) of azide sodalite. Thermal behavior of sodalite was also assessed by thermogravimetric method.
