摘要
以乙腈、丙酮、丁内酯和环己酮等作为溶剂对HMX进行重结晶获得不同形貌的结晶颗粒。扫描电子显微镜（SEM）结晶形态观察表明：溶剂对HMX的晶形有显著的影响，从乙腈和丙酮溶剂中结晶得到的HMX晶体透明度高，外形规则，结晶形态多为宝石状，而从丁内酯和环己酮溶剂结晶得到的HMX晶体分别为针状聚晶和块状聚晶。TG-DSC分析表明：结晶形态对炸药的热安定性有较大影响，颗粒宝石状结晶的热安定性最好。
The different morphologies of HMX crystals are obtained from recrystallization with various solvents such as acetonitrile, acetone,butyrolacetone and cyclohexacetone. The SEM photographs show that the solvents have great effect on the morphology of HMX crystals and the crystals grown from the acetonitrile and acetone solution have more regular shape and uniform size. The TG-DSC analysis reveals that the HMX morphology has great effect on its thermal stability.
