    Barium Hydroxide Octahydrate CAS 12230-71-6

    Barium Hydroxide Octahydrate (CAS 12230-71-6) is a translucent, white crystalline inorganic powder known chemically as caustic baryta, primarily utilized as a specialized strong base in the manufacturing of lubricating greases, plastic stabilizers, and phenolic resins. This Barium hydrate compound functions as a highly effective saponification agent in Barium dihydroxide octahydrate reactions, reacting with fatty acids to produce durable barium soaps that provide heat resistance and mechanical stability to industrial lubricants used in high-temperature machinery. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

    Product Description

    Barium hydroxide

    aliases： Barium hydroxide, octahydrate; barium hydroxide octahydrate; barium hydroxide octahydrate; Barium hydroxide (octahydrate)

    CAS RN： 12230-71-6

    EINECS No. 241-234-5

    Molecular formula: Ba(OH)2·8H2O

    Molecular amount: 315.46 69

    Physical properties
    Appearance and properties of barium hydroxide: white powder
    Barium hydroxide molecular weight: 171.35
    Melting point of barium hydroxide: 350°C, decomposed into barium oxide at temperature above 600°C.

    Barium hydroxide crystalline hydrate: molecular weight 315.47, is a colorless monoclinic crystal, relative density 2.18, melting point 78°C, boiling point: 780°C, heat loss water becomes anhydrous barium hydroxide.

    Barium hydroxide density：Relative density (water=1)2.18 (16°C)

    Application: used in chemical, light industry, medicine and other industries, making special soap and pesticides, also used in hard water softening, beet sugar refining, boiler descaling, glass lubrication, etc., used in organic synthesis and barium salt preparation, as a multi-performance additive in the petroleum industry, etc.

    Most of the alkalis are insoluble in water, barium hydroxide is one of the alkalis soluble in water, and the alkalis soluble in water are: lithium hydroxide, sodium hydroxide, potassium hydroxide, rubidium hydroxide, cesium hydroxide, barium hydroxide, strontium hydroxide, calcium hydroxide (slightly soluble, regarded as soluble in water), ammonia (solute is ammonia) Barium hydroxide solids are very easy to deliquescence in air, and then form barium carbonate and water with carbon dioxide. At 20°C, the solubility in 100g of water is 3.89g.

    FAQ - Technical & Supply Chain

    • Q:

      Is Barium Hydroxide Octahydrate (CAS 12230-71-6) chemically interchangeable with the Anhydrous form?

      A: No, this octahydrate form contains eight water molecules (Ba(OH)2·8H2O ) and has a significantly lower melting point (78°C) compared to the anhydrous version, making it more suitable for low-temperature aqueous reactions but unsuitable for water-sensitive processes.
    • Q:

      What is the specific role of this chemical in grease production?

      A: It acts as the alkaline agent that neutralizes fatty acids to form the barium soap thickener matrix, which imparts water resistance and high shear stability to the final lubricating grease.
