XRD in transmission geometry with controlled temperature and relative humidity

In situ study of clay swelling

The use of the Empyrean diffractometer in combination with the Anton Paar MHC-trans chamber enables us to characterize in situ the swelling of clay minerals at variable temperature and relative humidity conditions.

By definition X-ray diffraction is the most comprehensive tool to study clay swelling. The measurements can be performed both ex situ and in situ, with the latter undoubtedly being a more accurate probe. Here we present an in situ comparative study of the swelling of montmorillonite and corrensite clays in a wide range of temperature and relative humidity.
