Resumen
[EN]A montmorillonite has been intercalated with Al3+ polycations, using concentrated
solutions and clay mineral dispersions. The reaction has been assisted by microwave radiation,
yielding new intercalated solids and leading to Al-pillared solids after their calcination at 500 C.
The solids were characterized by elemental chemical analysis, X-ray diffraction, FTIR spectroscopy,
thermal analyses, and nitrogen adsorption. The evolution of the properties of the materials was
discussed as a function of the preparation conditions. Microwave treatment for 2.5 min provided
correctly pillared solids.
