Effect of Bi2O3 on Structure and Properties of Zinc Bismuth Phosphate Glass |
| 초록 |
Glasses composition (50-2x)ZnO-xBi2O3-(50+x)P2O5 (x=0-20mol%) have been prepared. Particularly to examine the effect of structure and properties in phosphate glass system by change of Bi2O3 content, the present work studied about ZnO-Bi2O3-P2O5 glass. As a method to expect the relation between structure and properties, the structure was measured by FT-IR analysis. And the glasses were respectively confirmed to density, glass transition temperature (Tg), molar volume and optical absorption edge through structural change of glasses. Tg, density and molar volume increase with increase in Bi2O3 content in glass. The optical absorption edge was determined from the optical absorption spectra of the polished samples recorded at room temperature and has been associated with the structural changes occurring in these glasses with increase in Bi2O3 content. The FTIR spctra have been recorded in the spectral range from 400 to 1400 cm-1. The structural investigations based on these spectra show the rapid depolymerization of phosphate chains with increase in Bi2O3 content and formation of P-O-Bi bonds. Also, Bi is incorporated as BiO6 octahedra in the glass matrix. |
