| Zusammenfassung: | A method for improving abrasion resistance of sodium perborate tetrahydrate crystals prepared by reacting sodium metaborate with hydrogen peroxide in an aqueous slurry crystal growth medium, the improvement including highly supersaturating the aqueous slurry crystal growth medium. Also, an agent such as an excess of caustic may be added to the aqueous crystal growth medium to limit the growth rate of individual crystals. |
