Barium Hydroxide is an essential inorganic compound known for its strong alkaline properties, high reactivity, and broad application in chemical synthesis, wastewater treatment, glassmaking, and lubricant production. With growing demand across multiple industries, Barium Hydroxide remains a fundamental chemical for efficient, high-yield processes.

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

🏭 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.


Advantages of Using Barium Hydroxide

  • Strong Alkaline Reactivity: Delivers fast and complete neutralization.

  • High Purity Options: Available in ≥98% grades for critical industrial use.

  • Versatile Applications: Suitable for water treatment, chemical synthesis, glassmaking, and lubricants.

  • Stable Storage: Long shelf life under proper dry conditions.

  • Eco-Efficient: Effective in removing pollutants from industrial effluents.


⚠️ Handling and Safety Guidelines

While Barium Hydroxide is valuable industrially, it is toxic if ingested or inhaled in dust form. Handle with care:

  • Wear protective gloves, eyewear, and a dust mask

  • Store in a cool, dry, and ventilated area

  • Avoid direct contact with acids (may release toxic gases)

  • Follow local hazardous waste disposal protocols

Always consult the Material Safety Data Sheet (MSDS) for safety compliance.


📦 Packaging and Storage

Barium Hydroxide is typically packaged in:

  • 25kg PP woven bags with inner lining

  • 50kg fiber drums

  • 1-ton jumbo bags for industrial use

Ensure airtight sealing to prevent moisture absorption. Store away from acids, oxidizers, and flammable substances.


🌐 How to Choose a Barium Hydroxide Supplier

To ensure consistent quality and regulatory compliance, select a supplier who offers:

  • Certified product specifications (ISO, REACH, RoHS)

  • Batch-specific COA and SDS

  • Technical support and custom particle size options

  • Reliable global shipping and inventory

Partnering with a trusted manufacturer guarantees the efficiency and safety of your Barium Hydroxide operations.


📈 Why Barium Hydroxide Remains in High Demand

From wastewater purification to industrial-grade lubricants and high-performance glass, Barium Hydroxide is indispensable. Its ability to improve process efficiency, reduce impurities, and support sustainable manufacturing makes it a preferred chemical across global industries.

As industries shift toward cleaner, more precise technologies, Barium Hydroxide continues to be an integral part of the solution—ensuring quality, performance, and compliance.
