Abstract

The morphology of alumina was studied in laboratory experiments and in samples from the steel plant. Varying morphologies of alumina were observed after deoxidation and reoxidation but a clear discrimination between alumina formed by deoxidation or reoxidation was not observed. Local concentration gradients during the addition and dissolution of aluminium can explain different growth mechanisms which lead to the observed varying morphologies of alumina.
