The ammonium nitrate with 15 WT% potassium nitrate-ethylenediamine dinitrate-nitroguanidine system

The phase diagram for the ternary system ammonium nitrate(AN) with 15 wt% potassium nitrate(AN:15KN)-ethylenediamine dinitrate(EDD)-nitroguanidine(NQ) has been determined from room temperature to the melting point. The ternary eutectic temperature, measured for a mixture containing 67.24, 25.30, and 7.46 mole% of AN:15KN, EDD, and NQ, respectively, was found to be 98.9 ·°C. The binary phase diagrams for the systems AN:15KN-EDD, AN:15KN-NQ, and EDD-NQ were also determined.
