Etude structurale d'un hydrate 10 Å instable de kaolinite
Autor: A. Ben Haj Amara, A. Plançon, S. Jemai, J. Ben Brahim
Publikováno v: Journal of Applied Crystallography. 33:1075-1081
The treatment of KGa-1 kaolinite with dimethyl sulfoxide and ammonium fluoride heated at 383 K provides an unstable hydrated phase characterized by a 10 Å basal distance. When air-dried, this hydrate gives a dehydrated phase at 7.15 Å. The aim of t

Etude structurale par diffraction des RX et spectroscopie IR des hydrates 10 et 8.4 Å de kaolinite
Autor: A. Ben Haj Amara, S. Jemai, J. Ben Brahim, A. Plançon
Publikováno v: Journal of Applied Crystallography. 32:968-976
Two hydrated kaolinites, characterized by 10 and 8.4 Å basal distances, were synthesized by treating the kaolinite KGa-1 with dimethyl sulfoxide (DMSO) and ammonium fluoride (NH4F). The X-ray diffraction study was based on a comparison between the e
