Slag foaming is one of the most important phenomena in bath smelting processes, not only for iron and steel making but also for non-ferrous metallurgy.Mukai, one of authors in the present paper, expected that slag foaming might be caused by high speed evolution of small gas bubbles at the reaction interface such as a slag-metal interface and the bubble size evolued at the interface depends on the interfacial properties such as wettability between both liquids.<BR>Slag foaming behaviours have been directly observed in a carbon-iron silicate slag system and in a carboniron silicate slag-copper system using high temperature X-ray radiograph technique.CO gas evolution rates were also measured at the same time. Large bubbles at the interface between carbon and iron silicate slag were observed due to low wettability in the system, while relatively small bubbles were found in the carbon-iron silicate slag-copper system because CO gas was evolved at the interface between iron silicate slag and Fe-Cu-C alloy.It was also found that CO gas evolution rates in the carbon-slag system were slower than that in the carbon-slag-copper system.<BR>Slag foaming in the latter system occurred in the earlier stage comparing with the fomer system.It is clearly suggested that slag foaming was strongly affected by the interfacical properties of the system.
