Electromagnetic-Levitation and Its Application in High-Temperature Calorimetry
The electromagnetic levitation technique is presented. It is a useful method to measure the thermophysical properties of high melting metals. The levitation alloying calorimetry (LAG) is described. Using the associate model and the TAP series, the excess heat capacities of the systems Fe-V and Fe-Ti are calculated on the basis of the concentration and temperature dependent descriptions of their mixing enthalpies. The relation between the levitation alloying and drop calorimetry is discussed. Using the temperature dependent description of the mixing enthalpy given by the associate model, the enthalpy of the intermetallic compound Fe2Zr is calculated. The calculated and measured enthalpies were in perfect accordance.
