Water-insoluble ammonium polyphosphate was obtained by sintering of ammonium hydrogen orthophosphate and guanidine carbonate at 250-270 °C. APP was characterized by FTIR, Raman spectroscopy, DSC and NMR 31P. The structure of APP is net cross-linked with melamine formed by guanidine carbonate decomposition. APP decomposition temperature is over 300 °C and solubility is less than 0.2 g/100 g Hf).
