Taking aim at the need of granularity of RDX used for preparing plastic lead, the RDX was prepared by the nitric acid recrystallization;the influences of concentration, temperature and agitation of the nitric acid on granularity were analyzed;the nitric acid concentration of the initial crystallization mother liquid was determined. The tested results show that the RDX granularity can be controlled by controlling process conditions;the Fei's average granularities of the produced RDX are 13～15μm and 10～12μm respectively;the RDX quality can satisfy requirements of the user.
