Output of xrd analysis

  1. Feb 8, 2012 #1
    What are the various details and information (like particle size, crystal structure) that can be obtained and infered from xrd analysis of a copper nanopowder.

    Indexing of the xrd pattern gives the crystal symmetry (i.e., which reflections appear and which are forbidden).

    From peak positions (which give various d spacings for the crystal structure), the lattice parameter can be determined.

    From broadening of the peaks, Scherrer analysis (when instrumentational broadening is accounted for with a large-grained standard) can provide grain size estimates up to 100nm or so grains. Note that grain size is not the same as particle size.
