| Outline of Final Research Achievements |
For the purpose of describing the structure and properties of ionic materials such as molten salts, electrolyte solutions, and glasses, polarizable ion model (PIM) for interionic potentials has been being developed from first principles. In this work, we have applied the model containing dipole polarization to main oxide glasses, and shown it has some limitations in describing the structure. On the other hand, we have demonstrated that the model containing both higher order polarization and anisotropic repulsion can well describe the structure. These results show that PIM is useful for describing also more extensive materials. Furthermore, by optimizing the parameters for the model necessary for describing ionic oxide materials in general, the model functions have been established and generalized.
