Summary
The permanent and reproducible hysteresis loop obtained in the sorption of water vapour at 30° C. on alumina gel has been scanned by traversing the loop from various points on the sorption and desorption curves.
The general characteristics obtained on scanning are in conformity with those of other systems, silica gel-water, titania gel-water, silica gel-carbon tetrachloride and ferric oxide gel-carbon tetrachloride.
These characteristics form a convincing evidence in support of the cavity concept.
