Mass spectrometric study of UO2–ZrO2 pseudo-binary system

The UO2–ZrO2 system at high temperature (T>2000K): importance of the meta-stable phases under severe accident conditions

“…2). Nevertheless, recent experimental results have shown that the solubility limit in the U 1Àx Zr x O 2 tetragonal phase is x = 0.8 ± 0.05 at 2025°C [18].…”

“…Their crystallographic structure is fluorite-like, with Fm3m (cubic) or P42/nmc (tetragonal) space groups. Many studies [10][11][12][13][14][15][16][17][18][19][20] have tried to determine domain of stability in temperature and in composition between the two crystalline forms.…”

Thermodynamic study of the uranium–vanadium system

“…Our apparatus has already been described by Gardie et al [7] and Baïchi et al [8]. A schematic view of the device and the Knudsen cell geometry is presented in [9].…”

Thermodynamic activity measurements of iron in Fe–Zr alloys by high temperature mass spectrometry

“…Our apparatus has already been described by Gardie et al [21] and then by Baïchi et al [22] who improved the method with a restricted collimation device in order to discard the detection of parasitic surface re-vaporizations [23]. The envelope of the four effusion cells was made of molybdenum and the four Knudsen cells (crucible and lid) were made of pure ceramic oxide, hypostoichiometric yttria, Y 2 O 3−x for the alloys or dense alumina, Al 2 O 3 for the reference (pure Fe).…”
