利用静电悬浮的非接触诊断技术测量了液体Gd的热物理性质。在1585K至1920K温度范围内，密度可表示为ρ(T)=77.41T×103−0.46(T−TM)+(kg·m−3)，其中Tm=11585K，体积膨胀系数为6.2T×10−5K−1。在1613K至1803K温度范围内，表面张力数据可拟合为γ(T)n=88.22x−0.097(T−Tm)(10−3N·m−1)，在相同温度范围内，粘度可拟合为η(T)n=11.7exp[1.4P×104R/(RT)](10−3PA·S)。
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 asρ(T) = 7.41 × 103− 0.46 (T−Tm) (kg · m−3) whereTm= 1585 K, yielding a volume expansion coefficient of 6.2 × 10−5K−1. In addition, the surface tension data can be fitted as γ(T) = 8.22 × 102− 0.097(T−Tm)(10−3N · m−1) over the 1613 K to 1803 K span and the viscosity asη(T) = 1.7exp[1.4 × 104/(RT)](10−3Pa · s) over the same temperature range.
