Preparation and Microstructure of Al-Intercalated Vermiculite

Abstract:

Crude vermiculite is used as raw materials, heat-treated for activation, leached with a complexing acid, exchanged with sodium solution, following contacted with polyhydroxyl aluminium solution. The Al-intercalated vermiculites are prepared by ion exchange. The phase and microstructure of the composite material are analyzed by means of XRD, TEM, TG-DSC, et al. The results reveal that the basal spacing of vermiculite expanded by intercalation of Al-species, and the interlayer of vermiculite inlaid with a large amount of nanometer Al-species particles.
