Application & Dosage

What is Barium Hydroxide?

Barium Hydroxide is an inorganic compound consisting of barium, oxygen, and hydrogen. The octahydrate form is generally supplied as a white crystalline solid.

Chemical formula: Ba(OH)₂
Common hydrated form: Ba(OH)₂·8H₂O
CAS No. (octahydrate): 12230-71-6

Barium Hydroxide produces a strongly alkaline solution in water and can neutralize acids effectively.

Key Properties

  • Strong alkaline compound

  • Reacts readily with acids

  • Forms insoluble barium sulfate with sulfate ions

  • Available in hydrated and anhydrous forms

  • Useful as a chemical reagent and synthesis intermediate

  • Suitable for selected industrial and laboratory applications

Barium Hydroxide Octahydrate

Barium Hydroxide Octahydrate is one of the most commonly supplied commercial forms. It contains eight molecules of water of crystallization.

The octahydrate should not be substituted directly on a weight-for-weight basis for anhydrous Barium Hydroxide because their molecular weights and active Ba(OH)₂ content differ.

Major Applications of Barium Hydroxide

1. Chemical Manufacturing
Barium Hydroxide is used as a raw material and reagent for producing various barium compounds and specialty chemicals.

2. Esterification and Organic Synthesis
It can be used as a strong base in selected chemical reactions, including hydrolysis and esterification-related processes.

3. Sulfate Removal
Barium Hydroxide reacts with sulfate ions to form insoluble Barium Sulfate (BaSO₄). This property can be utilized in specific chemical-treatment processes where sulfate precipitation is required.

4. Water and Wastewater Treatment
In controlled industrial applications, Barium Hydroxide can be used for pH adjustment and precipitation of selected anions. Treatment chemistry must be carefully designed because soluble barium compounds require appropriate containment and management.

5. Petroleum and Industrial Applications
Barium compounds have applications across petroleum-related and industrial chemical processes. Specific use of Barium Hydroxide depends on the process chemistry and required specifications.

6. Lubricating Greases
Barium compounds have historically been used in the manufacture of certain specialty lubricating greases and related formulations.

7. Laboratory Applications
Barium Hydroxide is used as a chemical reagent for analytical and research purposes, particularly where a strong alkaline medium is required.
