Cesium hydroxide (CsOH) is a chemical compound consisting of an ion of caesium and a hydroxide ion. It is a strong base (pKb=-1.76), much like the other alkali metal hydroxides such as sodium hydroxide and potassium hydroxide. In fact, caesium hydroxide is powerful enough to quickly corrode through glass.
C 1814 (OTTO) Cesium hydroxide, 99% - used in the preparation of porous cesium titanosilicates, which are potential ion-exchange materials utilized for radioactive wastes cleaning purpose.
