Which compound was diffused through porous barriers at Oak Ridge to separate uranium isotopes?
AUranium carbonate
BUranium nitrate
CUranium hexafluoride
DUranium dioxide
Answer & Solution
Correct answer: C. Uranium hexafluoride
Uranium hexafluoride is volatile, so its vapour could be forced through barriers where lighter U-235 molecules pass slightly faster.
