SPONTANEOUS REHYDROXYLATION OF A DEHYDROXYLATED CIS-VACANT MONTMORILLONITE

Abstract

The state of dehydroxylation was studied after heating a homoionic and cv montmorillonite at various temperatures for different times. Spontaneous rehydroxylation occurred under ambient conditions at a relative humidity of approx. 55%. The results indicate that heating rate and duration of heating are important to prepare dehydroxylated cv montmorillonite.
