Abstract

Cu3(C6H5O3)2 wasmixedwitholeicacidandRDXaccordingtoacertainproportiontopreparethereactant. Theobtainedmixedexplosiveswereignitedbythedetonatorsundernitrogenprotectioninanexplosionvesseltosynthesizecarbon- encapsulatedcoppernanoparticles.Thedetonation productswereblackpowders.Theshape,compositionandstructureofthedetonationproductswere characterizedbyusingatransmissionelectronmicroscope(TEM)andX-raydiffraction(XRD)analysis. TheXRDpatternsshowthatthecarbon-encapsulatedcoppernanoparticlesareofcubiccrystal structureandtheaverageparticlesizeis20.2nmindiameter.TheTEMphotographsdisplaythatthe carbon-encapsulatedcoppernanoparticlesareofsphericalshapeabout10~40nmindiameterwith3~ 5nmthickgraphiticcarbonoramorphouscarbonshells.Theresultsindicatethatthedetonationsoot consistsofcopperascores,andgraphiteandamorphouscarbonascarbon-coatinglayers.Meanwhile, theformationmechanismofthecarbon-encapsulatedcopperwastentativelydiscussed.
