Abstract: PURPOSE: A manufacturing method of minute circular shaped RDX particles is provided to obtain circular shaped RDX particles by using a RESS(rapid expansion of supercritical solutions) process. CONSTITUTION: A manufacturing method of minute circular shaped RDX particles comprises the following steps: introducing gunpowder material including RDX in a vessel(s110); forming RDX solution by introducing dimethyl ether(DME) compressed gas to the vessel and dissolving the RDX(s120); forming crystallized RDX particles by exhausting the RDX solution to the atmosphere and reducing pressures(s140); and collecting the RDX particle by separating thereof(s160). The crystallized RDX particle is a spherical particle having the diameter of 0.1-1 micro meter. The DME compressed gas is introduced to the temperature of 40-150 deg. Celsius and the pressure of 80-450 bar. The DME compressed gas is mixed with one or more gases selected from carbon dioxide, propane and chlorodifluorimethane and is introduced.
