Effect of electron beam on the structure and crystallization features of BaO−SrO−TiO₂−SiO₂ glass

Abstract

Glasses of BaO−SrO−TiO₂−SiO₂ after electronic radiation treatment of 50–1000 kgy were studied by means of IR spectra, DTA and visible light absorption method. The result shows that the glass structure is changed due to the formation of structure defect from oxygen vacancy and E′ color center which resultsd in the crystallization process and new precursors, and decreasement of T_g temperature and crystallization peaks by 20–50°C.

Keywords
