Corrosion of gamma-aluminlum oxynitride (AlON) by CaO-MgO-FeO-Al2O3-SiO2 melts corresponding to blast furnace slag was examined from 1693 to 1753 K under static and forced convection conditions. An intermediate layer was observed between the unreacted oxynitride and slag. After a certain time interval, the rate of the growth of this layer was found to be equal to the rate of the dissolution of the layer. Slag corrosion of NON is a strongly thermally activated process, the overall activation energy being 1002 kJ/mol. The rate of corrosion was found to be significantly enhanced by the addition of,,FeO.
