PROCESS FOR OBTAINING SUBMICRON MONOMODAL GRANULOMETRY HEXANITROHEXAAZAISOWURTZITANE CRYSTAL (CL20) CHARGES, THE SAME CHARGES AND THEIR USE AS SEEDING LOADS

摘要

The subject of the present invention is a process for obtaining (energy) charges of hexanitrohexaazaisowurtzitane (CL20 or HNIW) crystals of monomodal submicron granulometry (D50 1 μm), as well as the charges, which are, by themselves, likely to be d obtained by said method. It also relates to the use of said charges to seed solutions saturated with CL20 in order to obtain small crystals of CL20. The process involves continuously grinding a charge of hexanitrohexaazaisowurtzitane crystals with a particle size above the micron (D50 1 μm) suspended in a liquid; said grinding being carried out, with cooling, by multi-passage of the suspension (1) in a grinder (20) circulation, horizontal axis, attrition with grinding media (9) agitated.
