Abstract
Intercalation complexes of three different Hungarian kaolinites with h ydrazine and potassium acetate were investigated by FT-IR (DRIFT) spec trometry, X-ray diffraction, and thermogravimetry combined with mass s pectrometry. Differences were found in the thermal behaviour of the co mplexes as well as in the rehydration - reexpansion patterns of the he ated intercalates. An XRD method is proposed for the distinction of ka olinite and 7.2 Angstrom halloysite present in the same mineral.
