Abstract

The effect of swelling conditions on the vermiculite pore structure was studied by X-ray diffraction analysis, mercury porosimetry, and scanning electron microscopy. The closed porosity of the samples was estimated. A possibility for purposeful modification of vermiculite pore structure by varying the swelling temperature and heating rate was evaluated.
