As collected from internet search at different places:
[I] Yes . this sized globules can be handled under argon, in oil and/or in a dry room.Even in a dry environment, however, finely divided dry lithium powder will react with the oxygen in the air unless it is protected with an inert coating. Of course, coatings allow even finely divided lithium metal powder to be handled in a dry room environment for extended periods of time.
[II]Reactivity of lithium increases with surface area.
[III]Molten lithium is pyrophoric
[IV]Lithium should only be handled by trained personnel wearing
proper personal protective equipment.
[V] No doubt, solid lithium can be handled in open atmosphere at room
temperature, either coated in mineral oil or where relative
humidity is maintained below 50%.
[VI]BUT TO MAINTAIN BEST QUALITY, HUMIDITY LEVELS OF LESS THAN 2% ARE RECOMMENDED.
Dear sir,
Thanks for your valuable information. As you have mentioned that It can be handled under argon atmosphere so I have some confusion that If 1 mm metal granules bottle can be opened at room temperature? This is coarse particle but still as reactivity is very high so I have few doubts.
Make sure you do not use nitrogen as nitrogen can react with finely powdered lithium to form lithium nitride in a rather exothermic reaction which can melt through the bottom of flasks. I would alway suggest that lithium metal is handled under argon gas.
