Thermal behaviors during lithium diffusion in LiWO bronze studied by elastic and quasi-elastic neutron scattering.

Polycrystalline LiWO bronze has been synthesized by solid state reaction carried out in a silica tube at 10 MPa and 973 K. The sample is characterized by temperature-dependent neutron elastic and quasielastic scatterings. The room-temperature neutron powder data Rietveld refinement confirmed the space group 3̄ along with lithium occupancy found predominantly at the 6 crystallographic site.
