Description

Strontium hydroxide (CAS 18480-07-4 ) is a strong inorganic base used industrially for pH adjustment, neutralization, and as a strontium source in chemical synthesis. It is available in both anhydrous and octahydrate forms. Each form is suited to different processing requirements across various sectors. In water treatment, it neutralizes acidic effluents and precipitates heavy metal contaminants, supporting compliance with discharge standards. Electronics manufacturers use it in the production of strontium-based compounds for cathode ray tube glass and specialty ceramic formulations. It also serves as a precursor in synthesizing strontium salts. These salts include strontium carbonate and strontium nitrate, which are used in pyrotechnics and optical glass production. Sugar refining has historically used the compound to separate sucrose from molasses. This process occurs through strontianite precipitation, though this application is now limited. The product is supplied as a white powder or crystalline solid in both anhydrous and octahydrate forms. Technical grade is the standard commercial specification for industrial and synthesis applications. Packaging typically ranges from small drums to bulk quantities for large-scale manufacturing needs. Purity levels are commonly specified at 95% or higher depending on end-use requirements. This ensures consistent performance in chemical reactions and industrial processes requiring high-quality alkaline sources. Contact us for supply of Strontium hydroxide Request Quote
