Abstract

Aluminosilicate zeolites are formed in a novel reaction medium which contains a silicate source and an aluminum source in an aqueous alkaline solution wherein the Si/Al of the reaction mixture is at least 1.0 and which reaction medium further includes an additional electrolyte salt. The addition of the electrolyte salt provides nucleation sites for the zeolite so as to form very small crystals. In high silica reaction environments, it is possible to form high aluminum zeolites which contain occluded silicate and wherein the morphology of the zeolites comprise macroscopic aggregates of microcrystalline zeolites. The addition of the electrolyte salt can also decrease the reaction time or temperature needed for crystallization. The zeolitic compositions of this invention have outstanding capability to complex multivalent cations, especially calcium due to the high exchange kinetics of the microcrystellaline zeolite component and yet have the ease of handling due to the macroscopic aggregate assemblage.
