Simple pressure gauge for uranium hexafluoride.
A sensitive detector and pressure gauge for uranium hexafluoride in high-vacuum systems is described. Negative surface ionization of UF(6) occurs on ribbon filaments operated at temperatures too low for electron emission to be significant. The ion current measured on a cylindrical collector surrounding the filament assembly varies regularly with UF(6) pressure below 10(-3) Torr. Different filam...
متن کاملGas-Phase Reactions of Bare and Ligated Uranium Ions with Sulfur Hexafluoride
Reactions of bare and ligated uranium ions with sulfur hexafluoride were studied in a quadrupole ion trap mass spectrometer. Bare U+ was found to react rather efficiently with SF6 (k/kADO ∼ 0.4) to produce both UFn (n ) 1, 2, 3, 4) and SFn (n ) 1, 2, 3). Whereas the UF/SF6 reaction rate was essentially the same as that for U/SF6, both UF2 and UF3 were inert; this is attributed to a repulsive in...
متن کاملTheoretical Study of the Structure and Reactions of Uranium Fluorides
Uranium is an actinide metal mostly known for its use as fuel at nuclear power plants. Once the amount of fissile isotope (U) in nature is not enough for a chain reaction, uranium must be enriched in order to achieve roughly 4% of the 235 isotope. Therefore, it is converted into UF6, a gaseous compound, which can be used in isotope separation techniques (being centrifugation the most used and l...
متن کاملSynthesis and reactivity of bis(imido) uranium(VI) cyclopentadienyl complexes.
The bis(imido) uranium(VI)-C(5)H(5) and -C(5)Me(5) complexes (C(5)H(5))(2)U(N(t)Bu)(2), (C(5)Me(5))(2)U(N(t)Bu)(2), (C(5)H(5))U(N(t)Bu)(2)(I)(dmpe), and (C(5)H(5))(2)U(N(t)Bu)(2)(dmpe) can be synthesized from reactions between U(N(t)Bu)(2)(I)(2)(L)(x) (L=THF, x=2; L=dmpe, x=1) and Na(C(5)R(5)) (R=H, Me); these complexes represent the first structurally characterized C(5)H(5)-compounds of uraniu...
متن کاملAn insight into effect of surface functional groups on reactivity of Sphalerite (110) surface with Xanthate collector: a DFT study
The reactivity of the protonated and hydroxylated sphalerite (1 1 0) surface with xanthate was simulated using the density functional theory (DFT). The difference between the energy of the lowest unoccupied molecular orbital of the sphalerite surface and the energy of the highest occupied molecular orbital of xanthate ( was used to compare the reaction capability of xanthate with fresh and fun...
