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.

Precise identification of illite/smectite interstratifications by X-ray powder diffraction

TL;DR: In this article, three methods have been developed for the interpretation of X-ray powder diffraction patterns of glycolated mixed-layer illite/smectite which take layer-spacing variability into account.

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.

Swelling Properties of Synthetic Smectites in Relation to Lattice Substitutions

TL;DR: In this paper, synthetic clays were prepared hydrothermally at 300° to 350°C and 15,000 psi from gels with compositions calculated to give a series of octahedrally and tetrahedraally substituted, 2:1-type layer silicates with charges of 0.5N, 1N,1.5 n, 2N, 4N, 5N, 6N, 7N, 8N, 9N, 10N, 11N, 12N, 14N, 15N, 16N, 17N,
