Barium, one of the highly reactive alkali metals, is a
gummy purplish metal that forms a black oxide within seconds of being
exposed to air. ACI Alloys can supply pure barium sputter targets and evaporation pieces packed in argon, although the material is best packed in oil to prevent
Barium alloys may be stable in air.
