The wettability of graphite by the CaO-SiO_2-Al_2O_3 salgs containing different levels of iron oxide has been investigated by the sessile drop method at 1500-1600 deg C. The focus of the investigation is on the carbon/slag interfacial phenomena, which has a significant effect on the kinetics and mechanisms of iron reduction from the molten slag by carbon in the direct iron smelting process. The wettability results indicated significant effect of slag composition on the slag/graphite interfacial interactions.
