Abstract
Course attrition-resistant title cpd. (I) is made by reaction of Na metaborate (II) with H2O2 in an aq. suspension of seeds of (I) in a satd. soln. of (I). A clear supersatd. soln. containing 200-700 g/l (I) obtd. from (II) and H2O2, at 40-50 degrees C, is added to the rst. of the salt suspension in the crystallizer, and the process is then performed in known manner.
