# Is atom-clean aluminum active enough to react with alkali salts?

Thermally evaportated $\ce{Al}$ under high vacuum is free of oxidized species and highly active. But is it active enough to even substitute the alkali cationic metal in alkali salts, like $\ce{LiOH, NaOH, Cs2CO3}$. Here $\ce{Al}$ is directly depositely onto the salt substrate.
