Investigation of the physicochemical changes preceding zeolite nucleation in a sodium-rich aluminosilicate gel

The changes in composition and structure of sodium hydroxide rich aluminosilicate gel yielding zeolite A are studied. The studies have shown the unrivaled sensitivity of hyperpolarized (HP) [super 129]Xe NMR that is capable of identifying presence of small amounts of crystalline zeolite material in amorphous medium with detection limit extending below 1 wt%.
