Structure and properties of Na2O-TiO2-B2O3-P2O5 Glasses |
| 초록 |
Glasses in the system 30P2O5-30B2O3-40Na2O-xTiO2 (0 ≤ x ≤ 25 mol%) have been prepared by the melt-quenching technique. The more TiO2 content increases into the glass structure, which results in a decrease in the molar volume and an increase in the glass transition / softening temperature. Structural change were studied by 11B and 31P solid state NMR and Raman spectroscopy. The observed changes in the spectra and the properties of the studied glasses can be ascribed to several reasons and namely to the addition of TiO2 content the structure consists of a distorted Ti octahedral linked to pyrophosphate unit through P–O–Ti bonds. In these glass series the structural cohesion increases with TiO2, although a depolymerization in the original P–O–P network occurs. |
