Reaction Steps
About 100 parts by weight of a commercial melamine borate powder are added to about 100 parts by weight of concentrated aqueous ammonia containing about 25% ammonia while agitating. The mixture is reacted for 12 hours at ambient temperature and pressure. The melamine borate is hydrolyzed into smaller molecules and the ammonia radical reacts with the oxyacid boron radicals thereby producing an ammonium melamine salt of polyboron oxyacid and polyammonium melamine salt of polyboron oxyacid. It is then dried and pulverized into a fine powder.
