- I have some chips of Calcium that are badly oxidized. I am wondering
- if there is a simple way to clean them. I put them in a plastic bottle
- with N2 gas and sealed it for storage. I noticed that if I shake the
- bottle a lot, the oxide rubs off a bit. I suppose I could put glass chips
- in the bottle and shake for a day. Then I could take the Ca chips out in
- a glove box.
- Any better Ideas? Also, how can I store things like Ca, Na, K, and Rb
- without oil? Is Carbon-tetrachloride better? I need to put the chips in
- a high vacuum system and I don't want the oil around. I assume things like
- C-tet evaporate more easily.
