| Abstract Scope |
The Electro-Magnetic Levitator is one of the research facilities on-board the International Space Station which is operated by the European Space Agency for scientific investigations into solidification physics of metallic and semiconductor materials. It is used to observe structural evolution during the liquid-solid transition and to measure thermophysical properties in the liquid and undercooled state. The latter includes specific heat capacity, thermal conductivity, surface tension, viscosity, electrical conductivity, thermal expansion and hemispherical emissivity. The reduced-gravity environment hereby provides the best-possible experimental condition to arrive at highly accurate and reliable measurement data. This presentation gives an overview of the analytical methods (including modulation calorimetry and the oscillating drop method) that are being employed for these measurements. Different approaches are being considered and will be illustrated with measurement examples. Guidelines for the implementation will be given as well. |
