Abstract
Novel morphologies are provided for aluminosilicate zeolite ion-exchange materials useful for static water softening. The zeolites are provided in the form of large aggregates composed of submicron zeolite crystals. Rapid exchange rates, high hardness ion capacity and increased attrition resistance characterize the zeolite ion exchangers.
