摘　　要：为了提高弹药的爆轰性能,该文提出通过改变单质炸药的颗粒形态来提高炸药的装药性能。给出了重结晶法制备球形化RDX颗粒的实验原理和流程,测试了球形化RDX的晶体形状、热性能和热感度,以及以球形化RDX为基的熔铸炸药药柱密度。结果表明,与普通RDX颗粒相比,球形化RDX颗粒表面光滑,内部缺陷显著减少,熔化峰温提高1.57℃,分解峰温提高3.66℃;5 s爆发点提高1℃,安全性能有所提高;球形化RDX60/TNT40和RDX75/TNT25熔铸炸药的装药密度明显高于普通RDX60/TNT40和RDX75/TNT25熔铸炸药。In order to improve the detonation property of ammunition,the method of changing the shape of single-component explosive particle is adopted.The recrystallization principle and process of spherical hexogeon（RDX）is introduced.The crystal shape,thermal property,thermal sensitivity of the spherical RDX and the density of melt-cast spherical RDX/TNT and ordinary RDX/TNT explosive are tested.The results show that,compared with the normal RDX,the spherical RDX has less crystal defects and sleek surface,its melt peak temperature and decomposition peak temperature are seperately 1.57 ℃ and 3.66 ℃ higher,and the 5 s ignition point is 1 ℃ higher.The stability of spherical RDX is improved,and the densities of melt-cast spherical RDX60/TNT40 and RDX75/TNT25 are higher than that of ordinary RDX60/TNT40 and RDX75/TNT25.
