Barium Hydroxide Octahydrate is a white crystalline compound widely used across a range of industries, including food processing, chemical manufacturing, electronics, agriculture, and flame retardant applications.

Often listed under CAS numbers 22326-55-2 and 12230-71-6, it shares its core chemical structure with barium hydroxide monohydrate but differs in the number of water molecules incorporated into its crystalline structure.

With the molecular formula Ba(OH)₂·8H₂O, this compound exhibits air-sensitive and hygroscopic properties, meaning it absorbs moisture from the atmosphere and should be handled with care.

Its molecular weight is 189.47, and it has a density of 2.2 g/mL at 25°C.

Known for its high purity levels (minimum 99%), Barium Hydroxide Octahydrate is especially valued in specialized applications where consistency and cleanliness are critical.

One of the standout features of Barium Hydroxide Octahydrate is its appearance: a white granular crystal that is free-flowing and easy to handle in bulk.

This makes it convenient for transport, storage, and use in automated manufacturing systems.

Thanks to its solubility in hot water and strong basicity, it performs effectively in various chemical reactions and formulation processes.

It is often supplied in 25kg net bags, either kraft or plastic, and brands such as JINNUO provide certifications like ISO9001, ensuring quality and traceability.

This product is typically offered with a minimum order quantity (MOQ) of 20 tons, reflecting its industrial-scale use.

Additionally, samples are often available for customers to test before placing large orders.

Barium Hydroxide Octahydrate plays an important role in flame retardant applications, especially in coatings and plastics.

It works as a stabilizer and additive to enhance fire resistance in polymer materials.

When used in this context, Barium Hydroxide helps suppress smoke and flame propagation, making it a critical component in construction materials, textiles, and electronic housings.

It is also a favored additive in thermoplastics and PVC, where it contributes to the thermal stability and physical performance of the material.

In agriculture, it can be used in trace formulations as a soil conditioner or pH regulator, and in the food industry, only high-purity, food-grade forms are used under strict regulatory standards.

Another vital area of application is in chemical synthesis and reagent preparation.

Barium Hydroxide Octahydrate is often used to create other barium salts, purify sugar, and in the manufacture of lubricants and greases.

It serves as a key alkaline material in lab-grade reactions and is sometimes included in formulations for advanced ceramics and electronics.

Because of its high melting point (above 300°C) and reactive base properties, it can neutralize acids and assist in precipitation reactions where precise control of pH and ionic content is needed.

Its high purity and multi-grade classification—agriculture grade, food grade, reagent grade, electron grade, and medicine grade—enable it to serve both high-volume industries and precision science labs.

In terms of safety and handling, Barium Hydroxide Octahydrate requires proper storage and care due to its air-sensitive and hygroscopic nature.

It should be stored in a cool, dry place away from incompatible substances like acids and oxidizers.

Since barium compounds can be toxic if misused, particularly in food or pharmaceutical applications, usage must align with safety guidelines and quality certifications.

When used appropriately, especially in its food-grade or medicine-grade versions, it provides consistent performance and reliability.

Manufacturers and distributors typically offer detailed material safety data sheets (MSDS) to support proper handling and ensure safe industrial use.

In conclusion, Barium Hydroxide Octahydrate is a highly functional and versatile material with broad industrial appeal.

From flame retardants and chemical synthesis to food-grade and electronic-grade applications, its high purity, white crystalline form, and consistent performance make it an important asset in global manufacturing.

With a melting point above 300°C, a molecular weight of 189.47, and solid performance in both alkaline reactions and stabilizing systems, it is a preferred choice for professionals across various sectors.

The availability of samples, bulk supply options, and multi-grade classifications further support its growing role in modern industry.
