Caesium oxide It is a good electron emitter; however, its high vapor pressure limits its usefulness. Elemental magnesium reduces caesium oxide to elemental caesium, forming magnesium oxide as a side-product: CsO is hygroscopic, forming the corrosive CsOH on contact with water. Caesium oxide Caesium oxide (IUPAC name) or cesium oxide describes inorganic compounds composed of caesium and oxygen. The following binary (containing only Cs and O) oxides of caesium are known: CsO, CsO, CsO, and CsO. Both the oxide and suboxides are brightly coloured. The species CsO forms yellow-orange hexagonal crystals. Caesium oxide is used in photocathodes to detect infrared signals in
