      abstract     = {A process for production of micrometer-sized particles
                      composed of uranium oxide using aerosol spray pyrolysis is
                      characterized with respect to the various production
                      parameters. The aerosol is generated using a vibrating
                      orifice aerosol generator providing monodisperse droplets,
                      which are oxidized in a subsequent heat treatment. Zhe final
                      particles are characterized with microanalytical methods to
                      determine size, shape, internal morphology, and chemical and
                      structural properties in order to assess the suitability of
                      the produced particles as a reference material for
                      microanalytical methods, in particular, for mass
                      spectrometry. It is demonstrated that physicochemical
                      processes during particle formation and the heat treatment
                      to chemically transform particles into an oxide strongly
                      influence the particle shape and the internal morphology.
                      Synchrotron μ-X-ray based techniques combined with μ-Raman
                      spectroscopy have been applied to demonstrate that the
                      obtained microparticles consist of a triuranium octoxide
                      phase. Our studies demonstrate that the process is capable
                      of delivering spherical particles with determined uniform
                      size and elemental as well as chemical composition. The
                      particles therefore represent a suitable base material to
                      fulfill the homogeneity and stability requirements of a
                      reference material for microanalytical methods applied in,
                      for example, international safeguards or nuclear forensics.},
