Résumé

The kinetics and mechanism of pure zirconium corrosion in an iron-bearing borosilicate glass melt are investigated from 1230 to 1418 °C. The influence of immersion time and temperature on the corrosion layer morphologies is discussed. The corrosion mechanism is a multi-step process and is described using the Zr-Si-O-B phase diagram. Boron and silicon species contained in the melt are reduced at the zirconium contact and ZrSi_sB_b intermetallic compounds are formed while the Zr substrate is oxidized into ZrO_x. When the local melt fO₂ value induces the Fe⁰ precipitation, complex ZrSi_sB_bFe_f compounds are formed. The last step consists in the oxidation of ZrO_x into ZrO₂.
