Abstract

The crystallization of 2 3 2 Na O. SiO glasses doped with Cr2O3 (0-0.12-0.16-0.2–0.8-2-3-7mol%) has been investigated by UVVis-FTIR spectroscopy, XRD and SEM microscopy. The results showed that, By increasing content of chromium oxide, Transmission of light through sodium silicate glasses reduced due to ligand field and charge transfer mechanisms. Transmission of light through sodium silicate glasses with the presence of chromium oxide change and, also lead to formation of crystalline phases. More increasing of chromium oxide caused that light transmission in spectrum of these glasses being reduced, so that increasing chromium oxide up to 3% molar case that light absorbed, in which, by investigation chromium oxide effect on constituent units of glass lattice by means of infrared spectrum at 400-4000cm-1 region, it was identified that new peak at 640cm-1 has been appeared..
