The surface tension and viscosity of liquid niobium, zirconium, and titanium have been determined by the oscillation drop technique using a vacuum electrostatic levitation furnace. These properties are reported over wide temperature ranges, covering both superheated and undercooled liquid. For niobium, the surface tension can be expressed as sigma(T) = 1.937x10(3) - 0.199(T-T-m) (mN.m(-1)) with T-m = 2742 K and the viscosity as eta(T) = 4.50-5.62x10(-3)(T-T-m) (mPa.s), over the 2320 to 2915 K temperature range. Similarly, over the 1800 to 2400 K temperature range, the surface tension of zirconium is represented as sigma(T) = 1.500x10(3)-0.111(T-T-m) (mN.m(-1)) and the viscosity as eta(T) = 4.74-4.97 x10(-3)(T-T-m) (mPa.s) where T-m=2128 K. For titanium (T-m=1943 K), these properties can be expressed, respectively, as sigma(T)=1.557x10(3)-0.156(T-T-m) (mN.m(-1)) and eta(T) = 4.42-6.67x10(-3)(T-T-m) (mPa.s) over the temperature range of 1750 to 2050 K.
