Surface Tension of Titanium, Zirconium, and Hafnium

Abstract
The surface tensions of liquid Ti, Zr, and Hf at their melting points were measured in pure argon atmosphere by the drop‐weight method. A uniform longitudinal field induction coil was used to melt the sample rod tip. The average values obtained were 1390±40, 1400±40, and 1460±40 dynes/cm, respectively.
