the characteristics of supercritical fluid and principle of supercritical fluid extraction(SFE)
gas anti-solvent (GAS)
rapid expand supercritical solution (RESS) were introduced. The development of supercritical fluid recystallization technology used in manipulating ultrafine explosives desired and SFE developed for demilitarization of energetic material and RESS technology used in coating of energetic material were reviewed.Simultaneously
the problem existed in producing untrafine particle and changing property and further study about crystal nuclei and growth model and so on were proposed.
