Reaction rate of lithium with nitrogen?

Question

I know that lithium metal can react with nitrogen gas to form Li3N. Does anyone know what the rate of this reaction might be at STP or under slightly positive pressure?

Answer 1

have a look to this below:

Defect Structure of the Ionic Conductor Lithium Nitride (Li3N)Li3N forms ionic bonds; therefore, its valence formula. can be written as Li+N 3- (Schulz ... conduction comparable to Li3N in the temperature range 520 to ...
