Synthesis of DF (Deuterium FLuoride)

  1. Mar 4, 2016 #1
    Hello All,

    I am wondering if anyone knows a good synthesis for DF. I am trying to create a deuterated crystal for neutron diffraction studies (it is a hydrated crystal). The synthesis involves water and HF. I can buy D2O for the synthesis, but DF in D2O is a problem.

    If anyone can enlighten me on good precursors for DF I would appreciate it.
    FYI I work with HF regularly and am aware of it's hazards and safe handling practices.

    P.S. I know the standard synthesis for HF involves reaction of fluorite with sulfuric acid, however I obviously don't have D2SO4 either.

    How about BaF2+D2O+CrO3 -> BaCrO4 +2HF?

    This could work, thanks.

    I found that D2SO4 isn't much more expensive than D2O so I probably will end up buying some and using that to react CaF2 to form DF + CaSO4. I am going to try this method as well and see which gives me better results.
