| Abstract: | In the Li2O-WO3 and Li2O-WO3-B2O3 systems, high WO3 glasses were prepared by twin-roller quenching technique. The structure of glasses were studied by IE and Eaman examination. In Li2O-WO3 system, the content of WO4] tetrahedra increases with increases of content of Li2O and the content of WO6] octahedra increases with increase of WO3. In. the Li2O-WO3-B2O3 system, W6+ locates in the tetrahedrally coordinated oxygen ligands and participates in network when a small amount of WO3 is substituted for B2O3. When more WO3 is introduced, the content of WO4] is higher. WO6] octahedra emerge when the content of WO3 is very high. In the Li2O-WO3-P2O5 system, most of W6+ ions in tetrahedrally coordinated liganda and they exist in interstitial. PO4] tetrahedra and WO4] tetraheda or WO6] ootahedra can be linked by bridging oxygen when the content of WO3 is higher. |
