Description of key information

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE, study for Stability and reactivity is only required if stability of the substance is considered to be critical.
Expert Judgement
Dipotassium oxide/ Potassium oxide is stable under normal ambient and anticipated storage and handling conditions of temperature and pressure. Dipotassium oxide/ Potassium oxide is stable if stored under dry, cool conditions. Incompatible with oxidising agents.
However, it is hygroscopic and when exposed to moisture in air it decomposes.
Dipotassium oxide/ Potassium oxide is stable on storage and does not react with its container under normal conditions of use and storage.
Therefore testing for stability and reactivity towards container material does not need to be performed.
