•Corrosion of Al2O3–Cr2O3 refractory by glass has been studied.•Corrosion occurs via dissolution of Al2O3 followed by transportation towards glass.•Al2O3 is replaced by Fe2O3 and formation of Fe2O3–Cr2O3 solid solution takes place.•The Cr2O3 fraction remained un-corroded by the glass.
Hot corrosion behavior of Al2O3–Cr2O3 refractory by molten glass at 1200 °C under static condition was monitored. Glass-refractory interface was investigated by XRD, SEM and EDX analysis. After 36 h of testing, no visible change was observed, but SEM analysis revealed a corroded region of 315 μm. Corrosion occurs via dissolution of Al2O3 followed by mass exchange and formation of Fe2O3–Cr2O3 solid solution, which acts as a barrier to the molten glass. However, the Cr2O3 fractions of the refractory remained uncorroded.
