Abstract: The paper embodies characterization and rehydration of the clay from Bikaner district of Rajasthan. DTA and XRD indicated that the clay contained predominantly montmorillonite with kaolinite and quartz as impurities. The behaviour of the clay on dehydroxylation was found similar to an ‘abnormal montmorillonite’. DTA and TGA study suggested that the clay regained lost water completely on rehydration after being heat-treated up to 400°c, but the rehydration was comparatively poor when the clay was heated at higher temperatures. Maximum water adsorption was noticed for the sample heat-treated at 200°C.
