【摘要】 利用氧化-沉淀法成功制备出了磁铁矿纳米粒子,经过XRD技术表征,磁铁矿纳米粒子的平均直径约为45 nm,粒径分布狭窄。使用DSC技术研究了平均直径为45 nm的磁铁矿纳米粒子与常用的爆炸物黑索金(RDX),高氯酸三碳酰肼合镉(GTG),4,6-二硝基苯并氧化呋咱钾(KDNBF)和季戊四醇四硝酸酯(PETN)的热相容性。实验表明45 nm左右的磁铁矿纳米粒子与KDNBF热相容,与RDX及PETN不相容,与GTG严重不相容。更多还原

【Abstract】 To explore the new application of magnetite nanoparticles,thermal compatibility between magnetite nanoparticles and explosives in common use including hexahydro-1,3,5-trinitro-1,3,5-triazine（RDX）,cadmium three-carbohydrazide permanganate （GTG）,potassium 4,6-dinitro-7-hydroxyl-7-hydrobenzofuroxanate（KDNBF） and pentaerythritol tetra nitrate（PETN） was determined by DSC technique.The results show that Fe₃O₄ powders with 45 nm in diameter have fair compatibility with KDNBF,but poor compatibility with RDX and PETN,and bad compatibility with GTG.更多还原
