These sources work by applying a layer of alkali metal atoms on a low work function substrate, usually tungsten.
The technique coats a tungsten plug with aluminosilicate doped with an alkali metal, which is then sintered onto the tungsten.
These alkali metal heat pipes transferred heat from the heat source to a thermionic or thermoelectric converter to generate electricity.
From this acid other alkali metal salts can be prepared.
Saltiness and sourness are perceived when alkali metal or hydrogen ions enter taste buds, respectively.
As a hydride of an alkali metal, it is reactive towards even weak oxidizing agents.
The alkali metal peroxides and superoxides are powerful oxidizing agents.
This natural radioactivity became a basis for a mistaken claim of the discovery for element 87 (the next alkali metal after caesium) in 1925.
