Synthesis and thermal decomposition of sodalites Na8[SiAlO4]6·(XO4)2, X = Cl, Mn
Abstract
Sodalites containing the ions MnO4– and ClO4– have been synthesised and characterised by powder X-ray diffraction, IR, UV and solid state NMR spectroscopy; both materials may be heated to 500 °C before undergoing intracage decomposition to manganate and chloride ion containing sodalites, respectively.
