Anomalies in the Ethylene Glycol Solvation Technique used in X-ray Diffraction*
TLDR
In this paper, X-ray diffraction results are presented to show that some montmorillonites will not retain two layers of ethylene glycol in the interiayer space when dried under atmospheric conditions.Abstract:
X-ray diffraction results are presented to show that some montmorillonites will not retain two layers of ethylene glycol in the interiayer space when dried under atmospheric conditions. Diffraction data obtained from such samples of montmorillonite may erroneously be attributed to mixed layer minerals. Studies have shown however that this difficulty may largely be overcome by initially saturating the sample with ethylene glycol by the vaporization technique described, after which the sample is placed in a saturated atmosphere of ethylene glycol for a period of 12–24 hours to come to equilibrium and then irradiated.read more

Properties of Vermiculites and Smectites: Expansion and Collapse
TL;DR: In this paper, a number of different complexes of vermiculite and smectites were obtained depending on conditions of solvation, and the data indicate two discrete populations of the two types of complexes.
