Measurements of Vapor Pressures of Sc, La, and Ce by Multi-Knudsen Cell Mass Spectrometry

Thermodynamic measurement of La–Fe and Y–Fe alloys by multi-Knudsen cell mass spectrometry

“…Details of the equipment for Knudsen cell mass spectrometry used in this study are described elsewhere [15][16][17][18][19]. A cell holder in a vacuum chamber could hold four Knudsen cells, and ion currents from each cell or background could be detected individually by rotating the cell holder.…”

“…Using Knudsen mass spectrometry, the authors were successful in measuring the vapor pressure of RE metals and those in the alloys [15,16]. In this study, the activities of La and Fe in the La-Fe system, and that of Y and Fe in the Y-Fe system were determined by multi-Knudsen mass spectrometry.…”

Thermodynamic Measurements of Alloys and Compounds by Double Knudsen Cell Mass Spectrometry and Their Application to Materials Processing

“…We have, in past studies, applied the technique to various systems, including ironzinc 33) and rare earth alloys. 37,40,42,44,45) For example, activity measurements on copper-nickel (Cu-Ni) alloys are demonstrated here. Cu and Ni show a complete solid solubility at high temperatures as shown by the phase diagram 48) in Fig.…”
