Vermiculite from Weili, Xinjiang, was modified by sodium and intercalated by N-trimethylammonium bromide(CnTAB). The arrangement modeling patterns of CnTA⁺ in organic pillared vermiculite were studied by XRD and geometry size. The results revealed the different evolution routes about the arrangement model of organic cations in the vermiculite layer. The factors that affect the arrangement model of organic cations in vermiculite layer are the dosage of quaternary ammonium and the character of quaternary ammonium. It is lateral with little ammonium.
