Abstract
The submicron-RDX with spherical shape and uniform particle size distribution was successfully prepared by green mechanical demulsification technology .The morphology ,particle size distribution ,thermal properties and safety performance were characterized .The particle size distribution characteristics of submicron-sized RDX prepared were explored based on the fractal geometry theory ,which compared with the conventional recrystallization method .The results show that the RDX fabri-cated via the green mechanical demulsification technology is spherical shape with a median diameter of 470 nm ,and possesses better thermal stability and safety than that of RDX refined by the traditional recrystallization .In the double logarithm coordi-nates ,the weight cumulative percentage of RDX prepared using green mechanical demulsification technology and recrystalliza-tion has a linear relationship with the particle size ,and the fractal dimension D of the particles are 1 .54473 and 0 .82996 , respectively ,revealing that the submicron-sized RDX particles prepared by the former has a narrower particle size distribution , and better dispersion .关键词
