Abstract
Peak positions of silica structural bands, both in infrared absorption and reflection modes, were used earlier to measure the fictive temperature of silica glass. In the present study, the method was applied to determine the fictive temperatures of a soda‐lime silicate glass. For the silicate glass, the IR absorption spectra produced a broad structural band which made the precise determination of peak position difficult, and only the IR reflection band was used. Equilibrium peak positions of ∼1056 cm−1 IR band, due to Si‐O stretching, were found to be directly correlated with the fictive temperature of the soda‐lime silicate glass. The soda‐lime glass exhibited an opposite dependence of the IR band position on the glass fictive temperature as compared to silica glass.
