Abstract: The Ga-substituted saponite and its cross-linking materials with hydroxy aluminium oligmer were characterized by means of XRD, MAS NMR, IR, chemical analysis.The results indicate that the charge of tetrahedral sheet and pillaring density are related to the amounts of Gallium in tetrahedral sheet.The binding of pillar with sheet occured by the way of Ga-O-Alp linkage while the pillared Ga-saponite was calcined.But the basic framework of Al13 does not change.

Key words: Ga-substituted saponite, Cross-linking, MAS NMR
