Versuchsvorschrift

About 100 parts by weight of powdered borax (Na2B4O7.4H2O) are added to 100 parts by weight of concentrated aqueous ammonia containing 25% ammonia while agitating. The mixture is reacted for about 4 hours at ambient temperature and pressure thereby hydrolyzing the sodium borate and splitting the molecules into smaller molecules. The ammonia reacts with the sodium borate to produce an ammonium sodium salt of polyboron oxyacid and polyammonium sodium borate which is dried and pulverized into a powder with the general formula
