Barium carbonate is widely used in the ceramic and glass industries. It serves as an important raw material in the production of ceramic glazes, enamels, and porcelain, improving their strength, durability, and color quality. It is also used in the glass industry to enhance the properties of glass, such as reducing the expansion coefficient.
Barium carbonate is a key ingredient in the manufacture of certain pigments, particularly in the production of bright white pigments. It is also used in the production of specialized paints that require enhanced opacity and brightness.
Barium carbonate is used in water treatment applications, specifically in the removal of sulfate ions from industrial wastewaters. It reacts with sulfate compounds to form barium sulfate, which is then removed, helping to purify the water and make it suitable for reuse.
In chemical synthesis, barium carbonate is used as a precursor to produce other barium compounds. It is involved in the production of barium hydroxide, barium peroxide, and various other barium salts, which have diverse industrial uses.
Barium carbonate is employed in the rubber and plastics industries as a stabilizer and to improve the processing properties of various compounds. It enhances the durability and resistance of these materials to heat and UV light.
Barium carbonate is insoluble in water but soluble in acids, which makes it suitable for use in acid-based reactions and applications.
Store barium carbonate in a cool, dry, and well-ventilated area, away from incompatible substances. Ensure containers are tightly sealed to avoid moisture absorption. Keep the product away from acids and moisture, as it may react to form soluble barium salts.
