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
