Four thermophysical properties of both solid and liquid vanadium: the density, thermal expansion coefficient, molar heat capacity at constant pressure, and hemispherical total emissivity, are reported. These thermophysical properties were measured over a wide temperature range, including the undercooled state, with an electrostatic levitation furnace developed by the National Space Development Agency of Japan. Over the (l840-2240)K temperature range, the density of the liquid can be expressed as ρ(T)/(kgm - 3 )=5.46.10 3 -0.49.(T-T f u s )/K with T f u s =2183K, yielding a volume expansion coefficient of the liquid α(T)=8.9.10 - 5 K - 1 . Similarly, over the (1700-2180)K temperature range, the density of the solid can be expressed as ρ(T)/(kgm - 3 )=5.72.10 3 -0.52.(T-T f u s )/K, giving a volume expansion coefficient of the solid α(T)=9.1.10 - 5 K - 1 . The molar heat capacity at constant pressure of the liquid phase can be estimated as C p , m (T)/(JK - 1 mol - 1 )=48.78+2.75.10 - 3 (T-T f u s )/K over the (l825-2225)K temperature range if the hemispherical total emissivity of the liquid phase remains constant at 0.32 over the temperature interval. Over the (1350-2180)K temperature span, the hemispherical total emissivity of the solid phase can be expressed as T (T)=0.38-2.52.10 - 4 .(T/K)+9.90.10 - 8 .(T 2 /K 2 ). The enthalpy of fusion has also been measured as 26.5kJ mol - 1 .
