| Outline of Final Research Achievements |
Anisotropic phosphate glasses were prepared by stress-induced deformation of isotropic ones at the glass transition region, and their structural anisotropy formed in the amorphous structure was investigated from the viewpoints of direction dependent characterizations, elastic moduli and birefringence, and structural analyses, XRD and polarized Raman techniques. Molecular dynamics simulation of anisotropic glass was performed for structural modeling and analysis, which revealed that metaphosphate glass was unique to show the feature of anisotropic orientation in both partial structures of phosphate chain and modifying cation.
