Barium hydroxide properties

Barium hydroxide (chemical formula: Ba(OH)), also known as rehydrated barium or barium base, is an inorganic compound. It usually exists in the form of white or colorless crystals and is deliquescent, that is, it easily absorbs water in the air. Barium hydroxide soluble in water, dissolved to form an alkaline solution, with strong alkaline, the pH value of the solution can reach 14. This compound forms barium oxide and water when it is thermally decomposed, and barium carbonate precipitates when it encounters carbon dioxide.

Barium hydroxide use

Barium hydroxide has a variety of uses in industry and laboratories. It is widely used in analytical chemistry as an alkaline reagent. Barium hydroxide is an important intermediate for the production of other barium salts, such as barium carbonate, barium nitrate, etc. In oil and gas extraction, barium hydroxide is used to remove acid gases such as carbon dioxide and hydrogen sulfide. In the pharmaceutical industry, it is used in the manufacture of certain drugs. It is also used as an additive in glass and ceramic manufacturing to improve the corrosion resistance and thermal stability of products.

Barium hydroxide upstream raw material

The main raw materials for the production of barium hydroxide are barite (barium sulfate ore, BaSO-SO4) and coal. Barite at high temperature and coal reduction reaction to generate barium sulfide (BaS), and then barium sulfide dissolved in water, and then through the reaction with alkali to generate barium hydroxide. The main chemical reactions in the production process include:
