Abstract

Themorphology,composition,structure,grainsize,surfacearea,porevolumeandpore sizeofthedetonationproductswerecharacterizedbyusingdifferenttechniquesincludingtheX-ray diffraction(XRD),thescanningelectron microscopy(SEM),theX-rayphotoelectronspectroscopy (EDS)andthespecificsurfaceareaandporosityanalysis.Theresultsshowthatthelatticeconstantof theeutecticmeltparticlesystemcomposedbysilverandasmallaccountofcopperissmallerthanthat ofthepuresilver.TheXRDanalysesindicatethatthegrainsizeofthesilverparticlesintheeutectic meltsystemis15.9~22.2nm.TheSEManalysesrevealthatthebiggerellipsoiddetonationproduct particlesconsistofsomesmallsmoothsphericalsilverparticlesanddifferentcomponents,theFeOin whichcomesfromthedetonationvessel,theamorphouscarbonfromtheorganicexplosivecombustioninthesealvessel, andtheAlandSifromthedetonationfacility.Themorphologyinvestigations agreewiththeXRDanalyses.Tomakeitclearthatthedetonationproductscontainingsomecarbon powderactastheroleofadsorption,thesurfacearea,porevolumeandporesizewerealsodiscussed.
