This compound is not commonly used in experiments due to the high extraction cost of caesium and its reactive behaviour. It is known to have a higher selectivity to etch highly p-doped silicon than the more commonly used potassium hydroxide. This technique can form pyramids and regularly shaped etch pits for uses such as Microelectromechanical systems. It is an anisotropic etchant of silicon, exposing octahedral planes. Laboratory caesium hydroxide is typically a hydrate. ĭue to its high reactivity, caesium hydroxide is extremely hygroscopic. Cesium hydroxide fusion at 750☌ produces complete dissolution of glass pellets. The melting process is carried out in a nickel or zirconium crucible. Fused Caesium hydroxide dissolves glass by attacking silica framework and it has applications in bringing glass samples into a solution for analytical purposes in commercial glass industry and defense waste processing facility. It is the strongest of the five alkali metal hydroxides. Caesium hydroxide is a strong base (pK a= 15.76) containing the highly reactive alkali metal caesium, much like the other alkali metal hydroxides such as sodium hydroxide and potassium hydroxide. ![]()
