Abstract
The floating drop method has the potential for high-accuracy measurement of liquid–liquid interfacial tension. It was applied here to measure the interfacial tension between liquid Pb and a molten mixture of 8.9% LiCl, 50% NaCl, and KCl (mass%). The heavier Pb droplet floated on the lighter molten salt and enabled the acquisition of data at 673 K, 723 K, and 773 K under vacuum. The results agreed with previous reports. The temperature (T) dependence of the interfacial tension s was given by s = 459–1.27 T mN/m.
