The invention relates to a method for preparing high-quality energetic
crystal material fine particles. Various high-quality energetic
crystal material fine particle products, such as
pentaerythritol tetranitrate (PETN), cyclotrimethylene trinitramine (RDX), cyclotetramethylenetetranitramine (HMX),
hexanitrohexaazaisowurtzitane (CL-20), DADNE (FOX-7),
ammonium perchlorate (AP), and the like can be prepared by adopting an
ultrasound solvating-out
crystallization method in the traditional solvating-out
crystallization process. The high-quality energetic
crystal material fine particle product prepared by the preparation method disclosed by the invention has subglobular particle form, narrow
granularity distribution, average particle
diameter of 5-50 microns or so, transparent crystals, high
particle density, crystal theoretical density of more than 99.9 percent and obviously reduced
shock wave sensitivity and is used for pouring or pressing PBX (Plastic-bonded explosives). The method for preparing the high-quality energetic crystal material fine particles has the advantages of simple process flow and mild
reaction conditions and is suitable for
mass industrialized production.
