Caesium oxide

Caesium oxide (IUPAC name), or cesium oxide, describes inorganic compounds composed of caesium and oxygen. Several binary (containing only Cs and O) oxides of caesium are known.

Caesium oxide may refer to:

• (Cs₇O, Cs₄O, and Cs₁₁O₃)
• Caesium monoxide (Cs₂O, the most common oxide)
• Caesium peroxide (Cs₂O₂)
• Caesium sesquioxide (Cs₂O₃)
• Caesium superoxide (CsO₂)
• Caesium ozonide (CsO₃)
