What Type of Mineral Oil is Used to Store Some Specific Metals?

[Maget]

Hello
I have buy some Cerium, Barium, Lanthanum etc.
This metals come in mineral oil, but now I m confused, I don't know what type is used to store them and preserve so they not oxidize.
I want to have at hand in case I will need.
Have asked locally and nobody knows what I m talking.
Does someone know what mineral oil is used to store this metals?
Thanks for any input.

Hard to say, but it think it has to be vacuumed before use to ensure it is without air and moisture.

"paraffinum perliquidum" "paraffinum liquidum" or "paraffinum subliquidum" "paraffinum liquidum" will all serve the same purpose, some are more viscous than others but all will work equally well.

Will order some, thanks.

We always just used kerosene or diesel.

FYI, things like barium will always oxidize. It is extremely good at picking up N, O, H2O. Keeping a shiny sample of Ba is very difficult even with all schlenk technique.

There is a thread on science madness about keeping barium shiny, have a look there. I think in my opinion it is the same difficulty as keeping cesium silvery rather than golden--as in, good luck!

What about Solvent for paint or Acetone, can it work?
Not really looking to keep the shine.

I don't think acetone is appropriate. Aliphatic hydrocarbons only.

Will (this) work?
Thanks.
