During the hydration process and for RH up to 43%, the experimental profile is reproduced by interstratification
between the 0W and 1W phases with variable proportions, indicating the absence of a mono-homogeneous phase at 0W for humidity below 13% RH (Figure 3).
The kaolinite peaks were not affected by glycerol treatment indicating that there is no interstratification
with smectite layers in kaolinitic materials.
Additionally, the significance of layer insertion (interstratification
) on the structure and consequently the electrokinetic and wetting characteristics of the two layer silicates deserves further attention.
As reported by those authors, interstratification
accounts for the high CEC of basalt-derived soils containing smectite in southern Brazil.
The first cause of order or disorder in the structure of phyllosilicates and the resulting polymorphs and polytypes as well as of the interstratification
phenomenon lies in the chemical micromilieu acting during the crystallization.
Samples containing 10 [Angstrom] halloysite and with a 7 [Angstrom] kaolinite reflection skewed towards 10 [Angstrom] , which may be indicative of 10 A halloysite--kaolinite interstratification
, were heated at 105[degrees]C for 24 h to dehydrate the halloysite before obtaining a second diffraction pattern.

of two or more minerals are accepted as separate species if the kinds of layers, their relative proportions, chemical compositions, and regularity of interstratification
in three dimensions on a micrometric or nanometric scale have been well documented.
The characteristic 0.72 nm peak of kaolin (Kl) has a broad base, showing a probable interstratification
of Kl with HIV.
