It is recognized in the chemical industry by its CAS number 22326-55-2 and has a molecular weight of 189.47.

This substance is known for its distinct physical properties—most notably, its solubility behavior. BHMH is easily soluble in hot water but has limited solubility in cool water, alcohol, and acetone.

These characteristics play a vital role in determining its usability across different industrial processes.

Its appearance is typically white and granular, and it flows freely, making it relatively easy to handle in manufacturing environments.

The primary application of Barium Hydroxide Monohydrate is in the plastics industry.

It is extensively used as an additive in thermoplastics like phenolic resins and PVC (polyvinyl chloride).

BHMH functions as a stabilizer in PVC, improving the plastic’s resistance to heat and degradation.

In phenolic resins and rayons, it enhances thermal and mechanical properties, contributing to the durability and stability of the end product.

Because of these benefits, BHMH is an important component in the formulation of plastics that are expected to perform under stress or elevated temperatures, making it highly valued in construction, automotive, and consumer goods manufacturing.

Another significant use of Barium Hydroxide Monohydrate lies in the lubricant and grease industry.

Here, it acts as a general-purpose additive that enhances the efficiency and longevity of lubricating materials.

By improving the base characteristics of oils and greases, BHMH contributes to better wear resistance and temperature stability in machinery.

This application is particularly important in heavy-duty industrial settings where machinery must operate under high pressure and heat.

Additionally, it is used in the production of soaps and the fusing of silicates, showcasing its versatility across chemical manufacturing processes.

Beyond its role in manufacturing, Barium Hydroxide Monohydrate is essential in chemical synthesis, especially in producing other barium compounds and organic materials.

It is utilized in the sugar industry for refining processes, where it helps in removing impurities and enhancing the quality of the final sugar product.

In laboratories and chemical plants, BHMH serves as a reagent in multiple synthesis pathways, further demonstrating its broad utility.

This adaptability across both large-scale industrial and precision chemical processes illustrates the material’s value to various sectors.

In terms of specifications, high purity is a key factor in the effectiveness of BHMH.

The typical standard for Barium Hydroxide Monohydrate includes a Ba(OH)₂·H₂O assay of ≥99.0%, ensuring strong chemical activity.

Contaminants such as barium carbonate (BaCO₃) are restricted to ≤0.5%, while chloride (Cl) content must be ≤0.01%, and iron (Fe) is limited to ≤20 parts per million (PPM). The material’s insolubility in hydrochloric acid is controlled at ≤0.05%.

These strict specifications guarantee that BHMH performs consistently in industrial and chemical applications.

Overall, Barium Hydroxide Monohydrate is a highly versatile and valuable chemical compound widely used in plastics, lubricants, chemical synthesis, and other industrial applications.
