High-temperature calorimetry (1000°–1500 °C): new calorimeter detectors, procedures of mixing, and automatic data exploitation

Abstract

New calorimetric detectors for measurements of enthalpies of formation of liquid ionic and metallic systems in the temperature range 1000°–1500 °C have been designed and assembled. Much attention was paid in designing these new detectors in order to obtain reliable data. The mixing method, used with a stirring device, allows avoidance of parasitic thermal effects, and therefore improves the accuracy of the measured heat of mixing. The acquisition and treatment system of the calorimetric data is described.
