摘要：

Local structure around lead ion of molten PbF2-LiF system at various compositions (chi(PbF2) = 0.2, 0.4, 0.6, 0.8 and 1.0) were investigated by extended X-ray absorption fine structure (EXAFS) analysis, and composition dependence of the local structure was revealed. Coordination number and inter-ionic distance between 1st neighboring Pb2+-F- show similar to each other except at eutectic composition. In addition, structural change observed in EXAFS signals of pure PbF2 is reproduced by molecular dynamics simulation with polarization ion model. (c) 2005 Elsevier B.V. All rights reserved.
