摘要：

The aim of this work is to quantify the corrosion kinetics of high-alumina refractories by a binary slag (Al2O3 50 wt.% CaO 50 wt.%) and a ternary slag (Al2O3 45 wt.% CaO 45 wt.% SiO2 10 wt.%). The main objectives are i) to determine corrosion kinetics based on time-resolved X-ray diffraction at high temperature (1600 degrees C) combined with Rietveld quantification and (ii) to propose a reaction model based on the dissolution/precipitation/diffusion mechanisms. The results show that the corrosion process is very fast and involves an indirect dissolution mechanism with the formation of Al2O3/CA(6)/CA(2)/slag interfaces.
