Abstract: The maximum volumes of molten droplets stably levitated by an electromagnetic field in an axisymmetric inductor were determined for a number of rare-earth metals of the yttrium group (Y, Tb, Dy, Ho, Er, Yb). The experimental values of the maximum volumes are compared with values calculated using the surface tension, specific electrical resistance, and density of the rare-earth metals in the molten state.

Keywords: rare-earth metals, levitation melting, high temperatures, pure metals.
