Mechanisms of corrosion layer formation during zirconium immersion in a (Fe)-bearing glass melt
Source abstract
Abstract
Abstract 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 s B b intermetallic compounds are formed while the Zr substrate is oxidized into ZrO x . When the local melt f O 2 value induces the Fe 0 precipitation, complex ZrSi s B b Fe f compounds are formed. The last step consists in the oxidation of ZrO x into ZrO 2 .
