Metaphosphates are salts of metaphosphoric acid that react with ammonia to form ammonium metaphosphate. Ammonium metaphosphate is also made by reacting phosphorus pentoxide with ammonia.
Ammonium metaphosphate is a white fluffy powder with about 80% phosphorus and 17% nitrogen. Metaphosphoric acid or salts are often present in a polymerized form. In the vapor phase, the acid exists as a dimer and in solution it occurs as a trimer or tetramer
