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


Thermally evaportated 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 LiOH,NaOH,CsX2COX3. Here Al is directly depositely onto the salt substrate.
