Strontium hydroxide is used in the refining of beet sugar, where it helps separate sugar from impurities by forming soluble compounds with certain non-sugar components. It is employed in the production of other strontium-based chemicals, ceramics, and specialty glass requiring high heat resistance and specific electrical conductivity. Additionally, it removes silica from boiler recirculating water by reacting to form soluble strontium silicate, preventing scale buildup in industrial systems. In analytical laboratories, it separates carbonates from samples. Due to its strong alkaline nature, it neutralizes acidic waste streams, acts as a catalyst or reagent in organic synthesis, and is used in certain lubricants, pigments, and paints.
