The Low-Temperature High-Pressure Phase Diagram of Energetic Materials:I.Hexahydro-1,3,5-Trinitro-s-Triazine

摘要

The reaction phase diagram of hexahydro-1,3,5-trinitro-s-tria-zine(RDX)has been studied as a function of temperature and pressure by Raman spectroscopy to 29 GPa and temperatures ranging from 4 to 298 K.Three stable phases(alpha,gamma,and delta)have been found and their phase stabilities have been investigated.Phase boundaries were studied as a function of pressure and temperature,permitting a delineation of the various polymorph stability fields.A pressure-temperature reaction/phase diagram is constructed from the results of this study and compared to previous high temperature work.
