DIFFERENCES IN THE DEHYDRATION-REHYDRATION BEHAVIOR OF HALLOYSITES: NEW EVIDENCE AND INTERPRETATIONS

Joussein E.; Petit S.; Fialips C.; Vieillard Ph.; Righi D. (2006)

Two reference halloysites from New Zealand (Te Puke and Opotiki) were studied by X-ray diffraction under (1) various levels of relative humidity (RH) from 95 to 0% (dehydration), and (2) various temperatures increasing ...
GRAFTED ORGANIC DERIVATIVES OF KAOLINITE: II. INTERCALATION OF PRIMARY N-ALKYLAMINES AND DELAMINATION

Gardolinski J.E.F.C.; Lagaly G. (2005)

Kaolinite was intercalated with n-hexylamine, n-octadecylamine and n-docosanamine, using methanol-kaolinite as the precursor. The intercalation compound with n-docosanamine presented the largest basal spacing for a kaolinite ...
