Abstract
Thermophysical properties of molten refractory metals have been measured using an electrostatic levitation furnace. The developed levitation furnace could stably levitate molten samples at temperatures exceeding 3,000 degrees C. In addition, non-contact thermophysical properties measurement techniques have been implemented. Properties such as the density, the surface tension, and the viscosity have been measured over wide temperature ranges, including the undercooled region.
