Nano-oxide Black Suojin Ji Explosive Performance Impact Test Study

The nature of the nano-CuO, nano- LaCoO3, nano-Fe2O3, nano-Bi2O3, nano-TiO2, nano-Fe2O3 (5%La) and nano-Fe2O3 (5%Cu) is tested by the XRD. Using the DSC and the DTA study the chemistry of the RDX explosive mixture, containing those nano-oxides. Four presentative kinds of nano-oxides are selected because of their better result. They are 7nm-CuO, 10nm-CuO,nano-Fe2O3 (5%Cu) that metal Cu is adulterated and nano-LaCoO3 that is ABO3 compound nano-oxides.Using traditional method of lead disc and oil-pressure strain method research the output strength of the RDX explosive mixture, containing the nano-oxides. The experiments show that the output strength of the lOnm-CuO adding RDX explosive mixture is the largest and that of the 7nm-CuO adding RDX explosive mixture is the second. Through testing the sensitivity to impact, the sensitivity to friction and the sensitivity to heat of the RDX explosive mixture, containing the nano-oxides, the initial results indicate that the influence of the nano-oxides is relatively complex.The research have found that the nano-CuO have catalyzed effect on the chemical reaction of RDX explosive mixture.
