Description

Barium hydroxide octahydrate (CAS 12230-71-6 ) is a crystalline inorganic base supplied as a hydrated salt for industrial alkaline chemistry. It delivers strong, controlled basicity in applications where sodium or potassium hydroxides are unsuitable. Procurement teams source it primarily as a catalyst precursor, pH regulator, and flame retardant intermediate. In plastics and polymer processing, it acts as a catalyst or stabilizer precursor in PVC compounding and polymerization reactions. Water treatment operations use it to adjust pH and precipitate sulfate ions, particularly in systems where calcium-free effluent is a process requirement. This ensures high efficiency in specialized industrial filtration systems. The leather and textile industries apply it in deliming and fiber preparation baths. Its controlled alkalinity avoids the fiber damage often associated with stronger caustic alternatives during the manufacturing process. Mining and metals processing uses it to remove sulfate contamination from process streams. It is also used to condition leach liquors ahead of downstream recovery steps to ensure maximum yield and purity. Barium hydroxide octahydrate is supplied as white crystalline granules or powder. Standard commercial grades include technical and reagent-grade specifications, with purity levels typically ranging from 95% to 99%+. Packaging is commonly available in multi-wall bags or fiber drums suited to bulk industrial procurement. These formats ensure the stability and integrity of the chemical during long-term storage and transport. Contact us for supply of Barium hydroxide octahydrate Request Quote
