Abstract

DTA and EGA curves of montmorillonite and laponite treated with three metachromic dyes and of sepiolite and palygorskite treated with butylamine and pyridine were described, focussing on the contribution of the EGA to the interpretation of the different DTA peaks.

Zusammenfassung

DTA- und EGA-Kurven von nach dem Metachromverfahren behandeltem Montmorillonit und Laponit sowie von mit Buthylamin und Pyridin behandeltem Sepiolith und Palygorskit werden beschrieben. Schwerpunkt war der Beitrag der EGA zur Interpretierung der verschiedenen DTA-Peaks.
