Thermal compatibility between magnetite nanoparticles and explosives in common use

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'-hexa-nitrostilbene (HNS), hexadydro-1, 3, 5-trinitro-l, 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.
