Abstract
ORGANIC substances, either as neutral molecules or as cations, form ‘sandwich’ complexes with the expanding-lattice silicate minerals in which films of the organic substance a few Angstroms thick alternate with silicate layers 10 Å. thick. Recent work has shown that macroscopic vermiculite crystals complexed with butylammonium ions absorb large quantities of water and swell in the direction perpendicular to the plane of the silicate layers1,2.
