NEW DATA ON SEPIOLITE AND ATTAPULGITE
SEPIOLITE ATTAPULGITE DATA
font style='font-size:12px;'>
2011/11/15
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...
