Strontium hydroxide, with the chemical formula Sr(OH)₂, is an inorganic compound typically encountered as a white crystalline powder or octahydrate (Sr(OH)₂·8H₂O). It is a strong base, moderately soluble in water, and absorbs carbon dioxide from the air to form strontium carbonate. Its primary industrial applications are in the production of other strontium compounds, such as strontium carbonate and strontium nitrate. These compounds are key precursors in the manufacture of ferrite ceramic magnets for electronics and in pyrotechnics for producing brilliant red flames. It also serves as a refining agent in the sugar industry for separating sugar from molasses and finds niche use as a catalyst in certain chemical processes and in the preparation of specialty lubricating greases. As a strong base, strontium hydroxide requires careful handling. It is corrosive and can cause severe skin burns and eye damage. Proper personal protective equipment and storage in a cool, dry, and well-ventilated area are essential for safe use.
