| 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50 nm,粒径分布狭窄.使用DSC技术研究了平均直径为50 nm的磁铁矿纳米粒子与常用的爆炸物高氯酸钾（PP）,六硝基芪、 （HNS）,奥克托今（HMX）和二苦氨基二硝基吡啶（PYX）的热相容性,得到有意义的结论.实验表明,50 nm左右的磁铁矿纳米粒子与PP及PYX热相容,与HNS不相容,与HMX严重不相容.

| Abstract: | The magnetite particles (Fe3O4) were successfully prepared by an oxidation-precipitation method. XRD technique was used to characterize the size of the sample. It indicates that the average size of particles in diameter is about 50 nm with a narrow size distribution. To explore the new application of magnetite nanoparticles, thermal compatibility between magnetite nanoparticles and explosives in common use including potassium perchlorate (PP), 2,2', 4,4',6,6'-hexanitrostilbene(HNS), hexadydro-1,3,5-trinitro-1,3,5-triazine (HMX) and 3,5-dinitro-2, 6-dipicrylaminopyridine (PYX) was determined by DSC technique. The results show that Fe3O4 powders with 50 nm in diameter have fair compatibility with PP or PYX,but poor compatibility with HNS and bad compatibility with HMX. |
