Setup for in situ WAXS/SAXS studies of the formation and growth of Bi nanodroplets and the melting of Bi nanocrystals using synchrotron radiation

Abstract

The setup was designed for in situ studies of structural transformations in materials at high temperatures. It makes possible simultaneous recording of wide-angle X-ray scattering (WAXS) and small-angle X-ray scattering (SAXS) spectra from room temperature up to 1000 °C. The setup was installed in the National Synchrotron Light Laboratory SAXS beamline. It was applied to in situ studies of several structural transformations such as the formation and growth of liquid Bi nanodroplets embedded in a B 2O 3–Na 2O glass and the melting of Bi nanocrystals dispersed in the same glass matrix.
