Direct Determination of the Local Structure in Molten Alumina by High Temperature X-Ray Diffraction

摘要

A high temperature X-ray diffraction study of molten alumina has been carried out at 2363 K (2090℃). The local ordering parameters in molten alumina were estimated by using the interference function refining technique. Octahedrally coordinated aluminum is suggested to remain in the melt as the fundamental local structure.
