“…If AN is doped with a cation of nearly the same ionic radius, a solid solution will form which results in the suppression of phase transitions. The potassium cation (K + ) has an ionic radius of 1.33 Å, and the addition of K + results in a reduction in the IVIII transition, and raises the IIIII temperature range [13]. b) KDN is a member of the dinitramide anion ].…”

Potassium dinitramide (KDN) was incorporated in ammonium nitrate (AN) crystals in AN/KDN ratio of 90/10, 75/25 and 50/50 by a co-crystallization method. These mixtures were subjected to thermal decompositional studies (DSC-TG) using a Simultaneous Thermal Analyzer (STA). The catalysts used for the present studies were: i) cupric(II) oxide (CuO) and, ii) copper-cobalt based metal oxide (Cu-Co * ). For all catalytic samples, 2% by weight percent of catalyst was added to the total weight of the samples. Thermal decomposition studies were carried out for all the oxidizer samples prepared. Thermal decompositional studies were carried out at three different heating rates, i.e. 3 K/min, 5 K/min and 10 K/min, and the kinetic parameters were computed using the model free FlynnWall-Ozawa equation. It has been observed that 50% KDN addition resulted in complete suppression of endothermicity indicating total supression of the phase changes of AN in this temperature range. Further, it was noticed that CuO acts as a better phase stabilizer for AN as compared to Cu-Co * . However, Cu-Co * considerably increased the net exothermic decompositional heat release (J/g) of AN.

Das System AmmoniumnitratKaliumnitratEin Teil des binaren Phasendiagramms fur das System Ammoniumnitrat/Kaliumnitrat wurde im Temperaturbereich -55 "C bis + 185 "C bestimmt. Ergebnisse werden dargestellt fur das ammoniumnitratreiche Ende des Systems bis zu einem Gewichtsanteil von 30% Kaliumnitrat. Le systtme nitrate d'ammoniumlnitrate de potassiumOn a ktabli, pour la gamme de tempkratures allant de -55 "C B + 185 "C, une partie du diagramme d'kquilibre du systeme binaire nitrate d'ammonium/nitrate de potassium. Les rksultats sont prksentks pour la partie du systbme riche en nitrate d'ammonium jusqu'h une teneur pondkrale de 30% de nitrate de potassium. SummaryA portion of the binary phase diagram for the system ammonium nitrate-potassium nitrate has been determined from -55 "C to 185 "C. Results are presented for the ammonium-nitrate-rich end of the system up to 30 wt% potassium nitrate.
