| Research Abstract |
The purpose of this work is building-up of comprehensive analyses in highly integrated structure controlling of amorphous materials. Experiments such as diffraction, Raman spectroscopy, computer calculations were made for glasses and high temperature liquids, the optimized structures of which were obtained. 3-coordinated and 4-coordinated B-O units in borate glasses, trigonal bipyramids and trigonal pyramids of Te-O units in tellurite glasses, and octahedral complex ions in rare earth chloride-alkali chloride mixture melts were formed and furthermore some clusterings were also observed. Through these results, highly-developed prosessing of analyses was designed.
