Products - Barium Hydroxide Octahydrate

Barium hydroxide is available as colorless or white crystals. It is odorless and soluble in water. It is stable under ordinary conditions of use and storage. It is incompatible with acids, oxidizers, and chlorinated rubber. Barium hydroxide is corrosive to metals such as zinc. Barium hydroxide is very alkaline and rapidly absorbs carbon dioxide from air, becoming completely insoluble in water. Barium hydroxide is used in analytical chemistry for the titration of weak acids. Barium hydroxide is used in organic synthesis as a strong base. Barium hydroxide decomposes to barium oxide when heated to 800C.

Barium hydroxide octahydrate is extensively used in the manufacturing of barium salts and barium organic compounds; In manufacture of alkali, glass; in synthetic rubber vulcanization, in corrosion inhibitors, pesticides, sugar industry; boiler scale remedy; refining animal and vegetable oils; softening water. Catalyst in organic synthesis.

Barium soap greases possess both of the desired characteristics for grease applications; i. e. high melting point and high resistance to emulsification when in contact with water, being substantially insoluble when compared to calcium and sodium soaps.

Better lubricating efficacy.

It crystallizes from water (1mL/g) and readily absorbs CO2 from air. It efflorescens to the monohydrate. It dehydrates to Ba(OH)2 in dry air at 100C. An aqueous solution (baryta water) absorbs CO2 to form a white precipitate of BaCO3.
