摘要: 以乙酸铜为前躯体,并与液体石蜡和黑索今(RDX)炸药充分混合,在真空爆轰反应容器中引爆,制 备球状纳米铜晶。采用透射电镜(TEM)、X射线衍射(XRD)研究了爆轰产物的形貌和成分,同时通过Raman 光谱仪对爆轰产物中碳的结构进行了分析。结果显示,纳米铜晶具有较完整的球状结构,颗粒表面光滑,直径 集中分布在150~200nm 之间。爆轰法可为制备圆整度好的纳米铜提供一种简单、快捷的方法。Abstract: LiquidparaffinandRDXexplosiveweremixedintocopperacetateusedasaprecursor.The well-proportionedmixturewasinitiatedinadetonationreactioncontainerthatwasvacuumedtoprepareperfectsphericalnano- coppercrystalparticles.Themorphologyandcompositionofthedetonationsootwereanalyzedbytransmissionelectronmicroscopy (TEM)andX-raydiffraction (XRD).
