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 gamma(T)/(10(-3) N/m) = 1935 - 0.27 {(T - T-m)/K} with T-m = 2183 K. Over the same temperature span, the viscosity can be expressed as eta(T)/(10(-3) Pa . s) = 1.23exp[2.27 . 10(4)/(RTK-1)], where R is the gas constant. (c) 2010 Elsevier Ltd. All rights reserved.
