A RANDOM INTERGROWTH OF SEPIOLITE AND ATTAPULGITE
SEPIOLITE ATTAPULGITE RANDOM INTERGROWTH
2011/11/15
The smectic clays from Cabo de Gata region, Almeria, Spain, are composed mainly of montmorillonite, but they contain appreciable quantities of fibrous clay minerals, some of which are of the palygorsk...
It has been demonstrated that ferric iron is the principal source of the oxidizing action of the surface of attapulgite clay. The extent of oxidizing action in a- given time (the oxidizing power) has ...
Hydrothermal studies have failed to yield synthetic attapulgite or sepiolites in the system MgO-AI~O3-SiOr-H~O. However, the natural minerals can be decomposed to yield montmorillonoids by mild hydrot...
