Abstract

A light, bulk density (about 0.3-0.6 g./cc.) sodium perborate having a particle size larger than about 60 mesh is produced by reacting together an aqueous sodium metaborate solution with hydrogen peroxide in the presence of externally prepared, prismatic, seed crystals of sodium perborate tetrahydrate.
