The authors studied by means of differential thermal analysis and measurements of electric conductivity in continuous current and under atmospheric pressure, the reactions of dehydration and dehydroxylation of the following clay minerals : kaolin, montmorillonites, illite, glauconite, sepiolite, attapulgite and muscovite.Les auteurs ont étudié, par A. T.D. et mesures de conductivité électrique en courant continu, et à la pression atmosphérique, les réactions de déshydratation et de déshydroxylation des minéraux argileux suivants : kaolin, halloysite, montmorillonites, illite, glauconie, sépiolite et attapulgite, ainsi qu'un mica muscovite. Les réactions de déshydratation à basse température (60 < 0 < 150°C) se manifestent par une légère cro...
