| Abstract: | The preparation methods of ammonium polyphosphate are introduced including ammonium phosphate method, phosphoric acid-urea method, urea phosphate method, ammonium phosphate-urea method, phosphoric acid method, and ammonium phosphate-phosphorus pentoxide synthesis method. The degree of polymerization is low by ammonium phosphate method, phosphoric acid-urea method and phosphoric acid method, which can be used as fertilizer with the high solubility and neutral pH value. The degree of polymerization is high by ammonium phosphate-urea method and ammonium phosphate-phosphorus pentoxide synthesis method, which can be used as flame retardant. |

| Keywords: | ammonium polyphosphate production technology degree of polymerization agricultural fertilizer flame retardant |
