Thermal analysis of the phases of HMX using X-ray diffraction

M. Herrmann, W. Engel and N. Eisenreich

Abstract

The 4 phases of HMX and its transitions were investigated using X-ray diffraction. The phases were heated stepwise in a temperature range from 170 K to 510 K, measuring a diffraction pattern after each step.

The thermal expansion of the different phases and the volume changes during the phase transitions were obtained. Anomalies and strongly anisotropic expansions were observed with β- and γ-HMX.

The highest thermal expansion was found with γ-HMX, followed by δ-, β- and α-HMX. The highest volume change was observed with the βδ transition, followed by the αδ and the γδ transition.
