Special Review


High-pressure differential thermal analysis results are used to describe dehydration reactions for the clay-like materials of Na-rich montmorillonite, K-, Ca-, and Mg-exchanged montmorillonite, kerolite, and a high-pressure phase resembling talc/mica with excess water. Because sealed capsules may be used to contain fluids, it is possible to evaluate the role of H2O in these reactions. A separate paper (Part II) addresses the use of HP-DTA to understand dehydroxylation reactions in these materials.

Hochdruck-DTA Ergebnisse werden verwendet, um die Dehydratations-reaktionen für die tonartigen Materialien von Na-reichem Montmorillonit, von K-, Ca- und Mg-substituiertem Montmorillonit, Kerolit und einer durch Konfektionieren von Talkum/Glimmer mit überschüssigem Wasser entstandenen Hochdruckphase zu beschreiben. Da für Flüssigkeiten verschlossene Kapseln verwendet werden können, kann die Rolle von Wasser in diesen Reaktionen festgestellt werden. Ein anderer Beitrag (Teil II) beschreibt die Anwendung von HP-DTA bei der Untersuchung der Dehydroxylierungsreaktionen in diesen Materialien.
