Study on the Preparation of Ultrafine RDX Using the Technology of High-speed Impinging Streams

The ultrafine particle of RDX was prepared by using the technology of high-speed impinging streams. Studies were carried on the influence of impinging pressure and times on the particle size and distribution of RDX. The test results showed that the particle size and distribution of ultrafine RDX were influenced by the pressure and times of impinging, and the ultrafine RDX with narrow particle distribution can be prepared under certain conditions. Effective average particle diameter of RDX amounted to 79.6nm when the impinging pressure was 120MPa.
