Strontium Hydroxide Octahydrate


Strontium Hydroxide, or Sr(OH2), is a strong base with a pH of 13.5, and is most commonly found in colorless crystals. This strong base, as most bases are, is an extreme irritant of the respiratory tract if breathed, and of eyes and skin with contact. It is also dangerous if swallowed. However, even with such concerns, Strontium Hydroxide is a useful base for several different products.

Strontium Hydroxide is a clear deliquescent crystals that absorb carbon dioxide from air to form carbonate. It is soluble in hot water and acids, melts at 375 C (anhydrous), loses part of its water at ca. 100 C (octahydrate). It is used in refinery of beet sugar. It is used as a stabilizer in plastic. It is also used to make other strontium compounds.



Due to its reactivity to air, its affinity to ionic bonding and ionization, and its properties as a strong base, Strontium Hydroxide has several industrial applications. These include being a plastic stabilizer and a paint drier. As a heavy alkaline earth metal, it acts as a catalyst to bind plastics together, and causes paint to form a film when applied to help dry it faster.
