Abstract

Caesium aluminium silicates, caesium aluminium fluoride and aluminium fluoride were identified in a mixture obtained through the evaporation of kaolinite aqueous suspension with CsF. The mixture was studied by X-ray powder diffraction and IR spectroscopy. Two types of intercalation complexes of kaolinite were identified (A and B) which were characterized by c-spacings of ∼0.99 and 0.83 nm, respectively. Complex A seems to be an hydrated CsF intercalation complex, whereas complex B is a water intercalation complex, probably containing H3O+ and F−. It showed an IR absorption band at 3518 cm−1. The c-spacings of similar CsCl and CsBr complexes depend on the ionic radii. The intercalated ions are keyed into the ditrigonal cavities of the oxygen plane. A straight line plot of the keying values versus the ionic size indicates that keying is high for F−and decreases with increasing ionic size.
