     · The concentration of FeO is considered to be lower than in the rest of the slag at the interface between slag and metal, where reactions which form CO occur. This enables bubbles to form, since less FeO content results in a lower surface tension, which gives rise to the Marangoni effect. Thus, the ability to create new surfaces, which occurs when bubbles are formed in the slag, is facilitated ...
