Preparation of Nanoα-Fe2O3 and Its Influence on Impact Sensitivity of RDX

摘要

Nanoα-Fe_2O_3 was prepared via template-intervening process , Laser Granularity Instrument, XRD,TEM and IR were used to analyze the size , morphology , crystal and bond characteristic of the production. The result shows that the nanometerα-Fe_2O_3 has little size , perfect disperse property and strong absorb spectrum with wide frequency. The test experiment about impact security of the explosive RDX mixing different content nanometerα-Fe_2O_3 indicates that the influence of the nanometer α-Fe_2O_3 on the impact security is very obvious and the impact security of RDX increases following the increase of the α-Fe_2O_3 content in the compound explosive.
