Summary:After a brief review of the theory concerning the formation of a by a flat, vertical blade, the equipment and testing procedure used are described. The value of the interfacial tension between molten Al and flux (made of the equimolar mixture, NaCl--KCl) at 740 deg C is cm--1. The influence of the addition of various fluorides (NaF, KF, Na3AlF6) to the NaCl--KCl flux on the interfacial tension between Al and flux was then studied. For a given molar fraction of salt addition, the interfacial tension decreases when the resulting effect increases in the following order: Na3AlF6 < LiF < NaF results obtained with the addition of Na3AlF6 and NaF match obtained previously by Kurdyumov < etal < .8 refs.--AA
