Peeling of layered bentonites:
Pillaring is a special case of intercalation in which the
introduction of inorganic compounds into the interlayer space takes place. Regardless of the
properties, the modification process can be reduced to three main stages: 1) hydrolysis of
multinucleated metal ions hydroxy complexes (PHC) -pillar solution, 2) ion exchange, 3) heat
treatment of the modified material.
