The dimensionless Marangoni number, which controls the strength of this convection, contains additional thermophysical parameters. For liquid metals, these quantities are best measured under containerless conditions using electromagnetic levitation and non–contact diagnostic tools. In microgravity, small electromagnetic fields are sufficient to position a liquid sample. Some experiments can only be performed in such an environment, most others greatly benefit from microgravity and lead to results of higher precision. This paper reports on both terrestrial and microgravity measurements of thermophysical properties of undercooled liquid metals, including specific heat, density, surface tension, viscosity and electrical conductivity.
