摘要：
The structural position of Ti4+ ions in TiO2-Na2O-SiO2 glasses of xTiO2 · (100 − x) [2Na2O · 3SiO2] (0 ≤ x ≤ 30) composition has been studied with Raman spectroscopy. The analysis of spectra recorded has demonstrated that Ti4+ ions in the studied glasses can be in two structural groups—TiO5 and TiO6. Titanium ions with a coordination number of 5 are present in the structure of all Ti-containing glasses, whereas the highly coordinated state exists at x > 10 mol % TiO2.
