采用水热法制备了中空短棒状纳米Fe2O3,并用超声分散法将其与纳米Al颗粒复合为单金属氧化基超级铝热剂.利用X射线粉末衍射(XRD)、傅里叶变换红外(FTIR)光谱、扫描电镜及能量散射光谱仪(SEM-EDS)对样品进行表征.并运用差示扫描量热法(DSC)对比研究了超级铝热剂Al/Fe2O3、Al粉和纳米Fe2O3对环三亚甲基三硝胺(RDX)热分解特性的影响.结果表明:超级铝热剂的加入改变了RDX的热分解过程,并加剧了RDX的二次气相反应;随着超级铝热剂含量的增加,RDX的分解峰峰形发生了明显的改变;Al/Fe2O3、Al粉和Fe2O3对RDX热分解的作用主要表现为二次分解峰逐渐明显且峰温降低.
A hollow rod-shaped nano-sized Fe2O3 was prepared by hydrothermal method, and was compounded with nano-Al particles by ultra-sonic dispersion as a single metal oxide superluminal agent. The structure and properties were characterized by X-ray powder diffraction (XRD), Fourier transform infrared (FTIR) The samples were characterized by SEM, EDS and SEM. The effects of super-thermite Al / Fe2O3, Al powder and nano-Fe2O3 on the cyclotrimethylene Trinitramine (RDX). The results showed that the addition of super-thermite changed the thermal decomposition process of RDX and exacerbated the secondary gas-phase reaction of RDX. With the increase of super-thermite content, RDX . The effect of Al / Fe2O3, Al powder and Fe2O3 on the thermal decomposition of RDX mainly showed that the secondary decomposition peak became obvious and the peak temperature decreased.
