Zusammenfassung:Synthetic zeolite is stabilized to water by soaking it in a buffered acid solution for a prolonged time. The stabilized synthetic zeolite does not exhibit alkalinity when it is dispersed in water at room temperature for 24 hours or more, and exhibits improved flowability and almost constant ratios among Na, Al and O along the depth direction from the surface of the zeolite particles.
