Phase transitions of ammonium nitrate, NH_4NO_3 were observed by the dielectric measurement (1 kc/sec〜10 mc/sec) and by the differential thermal analysis. Four phase changes were confirmed between-100℃ and 130℃. Some of them had large thermal hysteresis. We did not observe the phase transition at -60.4℃ as previous worker reported. A large and sharp peak was observed on some specimens at 41℃ on heating, which was probably due to the small quantity of water adsorbed on its surface. This peak was never observed on cooling.
