Effect of Iron Slag on the Corrosion Resistance of Soda Lime Silicate Glass

Abstract

Soda lime silicate glasses containing different amounts of iron slag 30 % were prepared. The chemical durability of the prepared glasses was examined by immersion in HCl or HNO3 solutions at room temperature. The results show that the glass durability increases with increasing the amount of slag in the glass composition to a certain amount, then followed by a decrease in the glass durability. Various mechanisms of corrosion and the role of the mobility of cations and their leaching into solution, also the effect of time of leaching are discussed. The densities of all glass compositions were measured. The quantitative analysis obtained from infrared absorption spectra in the range of (400 4000) cm?1 in relation to the effect of corrosion on the absorption spectra has been studied in terms of structural concepts. The topography of the glass surfaces was observed by scanning electron microscopy (SEM). The concentration percentage of the ions present on the glass surface was determined by Energy Dispersive X-ray analysis (EDX). 2015, Springer Science+Business Media Dordrecht.
