A study of disorder in kaolinite
TLDR
In this article, X-ray powder diffraction patterns of kaolinites have been studied with especial reference to the region of the 02, 11, 11 band with a focus on the region in which the disorder between and within layers of a kaolinite can be detected.Abstract:
X-ray powder diffraction pattern_s of kaolinites have been studied with especial reference to the region of the 02, 11, 11 band. Satisfactory correlations with calculated patterns based on the layer structure of dickite can be achieved for a range of kaolinites if account is taken of disorder between and within layers. Some indication of the amount of disorder within a kaolinite can be obtained.read more

Stacking faults in the kaolin-group minerals: defect structures of kaolinite
TL;DR: In this article, the defect structure of kaolinite has been examined by examining the X-ray powder diffraction profiles for the 02,11 and 20,13 bands. And the defect structures of the nine samples were determined using the Hinckley index.

A crystallinity index for soil kaolins and its relation to parent rock, climate and soil maturity
J. C. Hughes,G. Brown +1 more
TL;DR: In this article, a new empirical index of crystallinity was obtained from the X-ray diffraction patterns of eight standard kaolins, which can be tentatively related to the presence of weatherable minerals in the soil and/or the length of the dry season.
Journal ArticleDOI
The Hinckley index for kaolinites
TL;DR: In this article, the authors examined the (02,11) X-ray diffraction band from a low-defect kaolinite from Cornwall (Hinckley index HI = 1·22) to determine the defect structure.

Bulk and surface properties of commercial kaolins
Maila Castellano,Antonio Turturro,Paola Riani,Tania Montanari,Elisabetta Finocchio,Gianguido Ramis,Guido Busca +6 more
TL;DR: In this paper, a correlation between surface acidity and structural and chemical properties of kaolins has been attempted, with a very small amount of medium acidic centers, which gave rise to a weak protonic acidity arising from bridging hydroxy-groups on exposed basal planes and silanol groups likely formed on non-basal planes.
