一般注記Thermophysical properties of several rare earth elements have been measured using electrostatic levitation techniques. The understanding of the nature and behavior of rare earth metals in their liquid phases requires accurate values of their physical properties. However, keeping the samples in their liquid phases free from contamination long enough to carry out measurements represents a formidable challenge. This is due to the high reactivity and contamination of these elements with a crucible or with a gaseous environment. The use of an electrostatic levitator in vacuum circumvents these difficulties and permits the measurements of the density, the surface tension, and the viscosity of these metals above and below their melting temperature. In this paper, the measurement methods as well as the levitation apparatus are introduced and the measured values are reported.
