Possibility of control of a separation of silicate layers in montmorillonite in the wide range of values of basal distance d001 is shown at intercalation of aluminum polycations of the different size. Change of concentration of complex forms of the polycations was reached by a variation of a hydrolysis ratio [OH-]/[Al3+] of the intercalating solution and its hyper thermal processing in the autoclave. Formation and efficiency of intercalation of "giant" ions [Al30O8(OH)56(H2O)24]18+ were inspected by the photometry, fluorescent spectroscopy, and small-angle X-ray diffraction. The cross-linking of silicate layers of montmorillonite in the course of a pillaring was fixed by the IR-spectroscopy.
