  • Patent number: 6214988
    Abstract: A process for preparing an HMX product comprises the steps of: (a) providing a granule that comprises a plurality of alpha-HMX particles and which has internal void spaces; and (b) sorbing at least one second material into the void spaces in the granule. The second material can be sorbed into the granules by using a vacuum to draw a gas phase comprising the second material into the granule. Alternatively, the second material can be sorbed into the granules by dissolving or dispersing the second material in a liquid solvent, contacting the solvent with the granules, and evaporating the solvent, whereby the second material is sorbed into the granules. Various second materials can be used, such as energetic materials and fuels.
