Thermophysical Property Measurements of Liquid Gadolinium by Containerless Methods.

Thermophysical properties of liquid gadolinium were measured using non-contact diagnostic techniques with an electrostatic levitator. Over the 1585 K to 1920 K temperature range, the density can be expressed as ρ( T) = 7.41 × 10³ − 0.46 ( T − T_m) (kg · m⁻³) where T_m = 1585 K, yielding a volume expansion coefficient of 6.2 × 10⁻⁵ K⁻¹. In addition, the surface tension data can be fitted as γ( T) = 8.22 × 10² − 0.097( T − T_m)(10⁻³ N · m⁻¹) over the 1613 K to 1803 K span and the viscosity as η( T) = 1.7exp[1.4 × 10⁴/( RT)](10⁻³ Pa · s) over the same temperature range.
