by thermal process
Ammonium polyphosphate 11-37-0 is a compound of monomer, dimer, trimer, tetramer, pentamer, hexamer, heptamer of ammonium phosphate. It is used as an high-efficient water soluble fertilizer with a healthy balance of quick-acting and slow-releasing. It also works as a very good chelating agent of metal ions in soil such as zinc, manganese, molybdenum, copper, helping to add activity of these metal ions. APP 11-37-0 is manufactured by thermal process.
