Surface tension and viscosity of molten vanadium measured with an electrostatic levitation furnace

Surface tension and viscosity of molten vanadium were measured over a wide temperature range by the oscillating drop method in an electrostatic levitation furnace. Over the (2023 to 2517) K temperature range, the surface tension can be expressed as γ(T)/(10−3 N/m) = 1935 − 0.27 {(T − Tm)/K} with Tm = 2183 K. Over the same temperature span, the viscosity can be expressed as η(T)/(10−3 Pa · s) = 1.23exp[2.27 · 104/(RTK−1)], where R is the gas constant.
