Abstract

The high-pressure, high-temperature ε-form of the widely used explosive RDX has been structurally characterized using a combination of x-ray and neutron diffraction techniques. A sample of this form has been successfully recovered to ambient pressure at 150 K and persists on warming to 220 K, at which point it transforms slowly to the α- form. The ε-form is denser than the α-form over the pressure range 0-3.6 GPa.
