University of Birmingham High temperature studies of sodalites unpub QD 10col_ephy Aluminosilicate sodalites Na\(_8\)(Al\(_6\)Si\(_6\)O\(_2\)\(_4\))Br\(_2\), Na\(_8\)(Al\(_6\)Si\(_6\)O\(_2\)\(_4\)Cl\(_2\), and Na\(_8\)(Al\(_6\)Si\(_6\)O\(_2\)\(_4\))I\(_2\), were synthesised and subsequently loaded with various amounts of silver by aqueous ion exchange to produce Na\(_8\)-Ag\(_x\)(Al\(_6\)Si\(_6\)O\(_2\)\(_4\))Br\(2\) with x = 0, 2, 4, 6, 8, Naz\(_8\)-Al\(_6\)Si\(_6\)O\(_2\)\(_4\))I\(_2\). Characterisation by X-ray powder diffraction and Rietveld refinements showed that for the chloride and bromide systems the substitution of silver for sodium causes a contraction of the unit cell and M-X bonds in the MX4 tetrahedral units in the sodalite cages, with an expansion of the distance of the metal from the framework oxygen atoms. This can be attributed to the increased covalent bonding in an Ag-X bond vs. a Na-X bond. High temperature X-ray powder diffraction studies were then carried out on these systems and it was found that they all displayed positive thermal expansion from room temperature up to 822ºC. The coefficients of thermal expansion for the bromide system showed a clear trend of decreasing with silver doping, but no clear trends for the chloride system or in the thermal expansion of the M-X or M-O distances in either system were found. 2011 2011-02 graduation eng This unpublished thesis/dissertation is copyright of the author and/or third parties.
