Anwendungen · 2 Einträge

BeschreibungStrontium Hydroxide occurs as an anhydrate whose prismatic, colorless crystals are deliquescent. A monohydrate and octahydrate are also known.Strontium hydroxide is slightly soluble in water but, surprisingly, the octahydrate is much more soluble. It is the latter that is supplied commercially for most applications.When the octahydrate is heated, seven waters of hydration are lost to form the monohydrate and finally the oxide.

VerwendenStrontium hydroxide [Sr(OH)2] is used to extract sugar from sugar beet molasses. It is also used in the manufacture of soaps, adhesives, plastics, glass, and lubricants that can be used in very high or low temperature environments.

synthetischePreparation Strontium hydroxide is prepared by treating strontium oxide with water: SrO + H2O → Sr(OH)2 Alternatively, Sr(OH)2 is made by heating strontium carbonate or strontium sulfide with steam at temperatures around 500 to 600°C: SrCO3 + H2O → Sr(OH)2 + CO2 SrS + 2H2O → Sr(OH)2 + H2S.
