Sepiolite - an overview ScienceDirect Topics

In attapulgite the strip width is of four tetrahedra and in sepiolite it is of six tetrahedra. The MgO 6 octahedra are arranged to give threefold strips leaving channels parallel to the fibre axis containing water molecules (Barrer, 1978). The idealised attapulgite composition for a half unit cell is Mg 5 Si 8 O 20 (OH) 2 (H 2 O) 4, 4H 2 O.

The physicochemical and catalytic properties of clay ...

Four clay materials, namely, bentonite, bleaching earth, attapulgite and sepiolite, were shaped into the cylindrical body by extrusion. Clays were characterized in depth by TEM, SEM-EDX, N 2 physisorption, pyridine FTIR, pH measurements, contact angle measurements, 27 Al MAS NMR, and the crush test. Catalytic properties were investigated in the citronellal cyclization as a
