The measurements of surface tension of the FeO-CaO-SiO2 ternary slags with and without the addition of ZnO, Al2O3, Na2O, P2O5 or CaS have been carried out at the temperature range from 1, 250°C to 1, 400°C by the modified “ring method”.<BR>The changes in surface tension with the reduction of zinc contained in the slags by blowing CO gas onto the melts have also been investigated with the same apparatus.<BR>The results obtained are summarized as follows: The surface tension increases with the increasing ZnO content. An addition of Al2O3 up to a few per cent seems to give little effect on the surface tension but the apparent increase has been observed in the region of the higher Al2O3 content.<BR>Both Na2O and P2O5 are found to be surface active in the ternary melt, while the effect of CaS is not clear.
