In this guide, we explore everything you need to know about Barium Hydroxide, including its properties, applications, handling precautions, and how to choose a reliable supplier.
🔍 What Is Barium Hydroxide?
Barium Hydroxide (Ba(OH)₂) is a white crystalline or granular solid that becomes slippery and strongly basic when dissolved in water. As a strong base, Barium Hydroxide is used in neutralization reactions, chemical manufacturing, and purification processes.
It exists in several forms, most notably:
Barium Hydroxide Octahydrate (Ba(OH)₂·8H₂O) — commonly used in industrial applications
Anhydrous Barium Hydroxide — highly reactive, used under controlled environments

Thanks to its strong basicity and solubility profile, Barium Hydroxide is widely used as a neutralizing and precipitating agent.
🏭 Industrial Applications of Barium Hydroxide
1. Water and Wastewater Treatment
Barium Hydroxide is used to remove heavy metals, sulfates, and fluorides from industrial wastewater through precipitation. It ensures regulatory compliance and eco-friendly discharge.
2. Glass and Ceramics
Acts as a refining agent in specialty glass and ceramic manufacturing. Barium Hydroxide improves transparency, strength, and thermal resistance.
3. Lubricating Greases
Used in the production of barium-based greases, which provide excellent thermal stability and water resistance for automotive and industrial equipment.
4. Plastic and Resin Stabilization
In PVC and phenolic resin production, Barium Hydroxide serves as a stabilizer to prevent degradation and discoloration.
5. Chemical Synthesis
Essential in the manufacture of other barium compounds such as barium salts (nitrate, carbonate, chloride), as well as for esterification and saponification reactions.
6. Petroleum Industry
Used to remove sulfur compounds and neutralize acidic intermediates in refining processes.
