摘　　要：介绍了一种能够制备高致密黑索今(RDX)晶体的方法。分析溶液浓度、结晶温度、搅拌速率、稀释速率等工艺条件变化对于RDX晶体密度的影响,制备了高致密RDX晶体。测试了高致密RDX晶体的晶体形状和缺陷、晶体密度、熔点、热性能和热感度。结果表明,采用特定工艺条件制备出的高致密RDX晶体和普通RDX晶体相比,密度增加0.023 g/cm3,高达1.808 g/cm3,是理论密度的99.56%;内部缺陷明显减少;熔点提高1.5℃,分解峰温度提高3.66℃;5 s爆发点提高1℃,安全性能略优于普通RDX.The preparation method of high density RDX was introduced.The influences of solution concentration,crystallization temperature,stirring speed and dilution rate on RDX crystal density were analyzed,and the high density RDX crystal was prepared.Its crystal shape,defects,density,melting point,thermal property and thermal sensitivity were tested.The results show that the high density RDX crystal density is up to 1.808 g/cm3,i.e.0.023 g/cm3 higher than that of the ordinary RDX,and reaches to 99.56% of the theory density and lacks of crystal defects.Comparing with the oridinary RDX,the high density RDX＇s decomposition peak temperature increases by 3.66 ℃,and ignition point increases by 1 ℃.The stability of high density RDX is better than that of the ordinary RDX.
