Why should I use argon gas in the glove box of lithium deposition equipment?

A typical glove box uses nitrogen. However, the glove box for lithium evaporators requires argon gas, which must also be high purity argon. Lithium reacts with nitrogen at room temperature and turns black.

How much pressure should I keep in my glove box?

It is recommended that the positive pressure inside the glove box should not exceed 15 millibar.
When using a glove, it is usually used at a pressure of about 3 to 5 millibars.
