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.
