Caesium chromate
Caesium chromate or cesium chromate, the caesium salt of chromic acid, is used to produce caesium vapour by reaction with silicon, boron, or titanium,[2] which is used to in the final stages of creating vacuum tubes; the caesium vapour reacts with the remaining gases, including nitrogen and oxygen.[3]
