Knudsen effusion mass spectrometry: application to the thermodynamic study of alloys

Résumé

The high temperature mass spectrometry method is a standard method for the study of chemical equilibria at high temperature and vaporization processes. For studies involving complex mixtures, as alloys, the multiple Knudsen cell –high temperature mass spectrometry is the very usefull device to perform thermodynamic activity measurements. The present work summarizes the evolution of the efforts done in order to elucidate the real nature of the collected effusion beams by any detectors including the mass spectrometers in relation with different physico-chemical phenomena occurring at the effusion orifice or near the edges of these orifices such as spurious molecular flows.We illustrate it with the results obtained about the iron–zirconium system
