A high pressure, high temperature study of 1,1-diamino-2,2-dinitro ethylene

Journal Article · · High Pressure Res.
We report a synchrotron energy-dispersive X-ray diffraction study of the novel high explosive 1,1-diamino-2,2-dinitroethylene at high pressures and high temperatures. Pressure was generated using a Paris-Edinburgh cell to employ larger sample volumes. High temperatures were created using a resistive graphite cylinder surrounding the sample. The PT phase diagram was explored in the 3.3 GPa pressure range and in the {approx} 400 C temperature range. We believe that the sample commenced in the {alpha}-phase and then ended up in an amorphous phase when the temperature increased beyond 280 C near 2 GPa, which we believe to be the {gamma}-phase. Further pressure and temperature cycling suggests that the sample transformed reversibly into and out of the amorphous phase near the phase line.
