Methods of non-contact calorimetry and their application to the measurement of the thermophysical properties of Zr-based liquid metallic alloys are described. These methods were developed for containerless processing in an electromagnetic levitation device under reduced gravity conditions. The experiments were performed in the course of the IML-2 and MSL-1 spacelab missions. Thermophysical properties measured include the specific heat, the enthalpy of fusion, the total hemispherical emissivity, and the effective thermal conductivity. Future applications will be focused on the measurement of thermophysical properties of liquid metallic alloys relevant to industrial processing.
