Synthesis, Infrared and Powder X-Ray Diffraction Studies of Mixed Halogen Sodalites of the Type Na8[AlSiO4]6Cl2-XIX and Na8-XAgX [AlSiO4]6Cl0.52

Abstract

The present work deals with the synthesis of mixed halogen sodalites of the type Na₈[AlSiO₄]₆Cl_2-xI_x that have been synthesized by using a low temperature hydrothermal technique. Infrared spectroscopy has been used for the confirmation of the framework structure. The structure of mixed halogen sodalite was established by X-ray Rietvelt refinement in the space group P43n . While, a silver containing derivatives, Na_8-xAg_x[AlSiO₄]₆Cl_0.52I_1.48, obtained through aqueous ion exchange method. In the present study more emphasis is given to find out the correlation of Si-O-Al angle and unit cell parameter with concentration of iodide for different sodalites of Na₈[AlSiO₄]₆Cl_2-xI_x (where, 0 < x < 2).
