99.2% Purity White Powder Barium Carbonate BaCO3 for Ceramic Tiles and Industrial Applications

Barium carbonate, chemical formula BaCO3, molecular weight 197.35. Hexagonal fine crystals or white powder. It is hardly soluble in water, with a density of 4.43 g/cm2 and a melting point of 1740°C (8820 kPa-90 atmospheres). Decomposes at 1450°C and emits carbon dioxide. Slightly soluble in water containing carbon dioxide, but also soluble in ammonium chloride or ammonium nitrate solution to form a complex, dissolved in hydrochloric acid and nitric acid to release carbon dioxide. poisonous. Used in electronics, instrumentation, and metallurgical industries. Preparation of fireworks, signal bombs, ceramic coatings, and auxiliary materials for optical glass. Barium carbonate is also widely used in ceramic tiles, etc.

High quality barium carbonate powder is used in the preparation of fireworks and signal bullets, and also used as an auxiliary material for ceramic coatings and optical glass.

Barium carbonate can be used in the manufacture of electronic ceramics, PTC thermistors, capacitors and other electronic components.

High quality barium carbonate can be used to make optical glass, picture tube glass, barium magnetic materials and capacitors, etc., as well as steel carburizing and metal surface treatment.

China barium carbonate powder can be used to make other barium salts and raw materials for ceramics, enamels, pigments, paints, rubber, and welding rods.

Used to prepare a solid carbonate electrode based on barium carbonate and strontium carbonate. It includes wire, barium carbonate or strontium carbonate, protective film, heat-shrinkable tube.

High quality barium carbonate can be used to remove sulfate from brine. It is mainly used for the removal of sulfate in the refining of brine in the chlor-alkali industry. It is the most economical method for removing sulfate in brine.

• Improving density and hardness: Adding an appropriate amount of barium carbonate can increase the density and hardness of ceramic tile raw materials, thereby improving the physical properties of the product, making the tiles more solid, wear-resistant, and having better compressive, bending, and impact resistance.
• Enhanced fire resistance: At high temperatures, barium carbonate can react with other minerals to form stable compounds, enhancing the fire resistance of ceramic tiles. For example, barium carbonate can react with silicon oxide to form stable barium silicate, which has a melting point of over 1600 ℃ and can effectively improve the high temperature resistance of ceramic tiles.
• Improving sintering performance: Barium carbonate can be used as a coloring agent for porcelain glazes and ceramics. Adding it to porcelain tile glazes can improve the coloring effect of glazes and promote the sintering process in ceramic technology. The addition of barium carbonate can also improve the sintering performance of raw materials, promote the bonding between mineral particles, accelerate the sintering of glazes and minerals, and improve process efficiency.
• Improving Whiteness and Glossiness: The high refractive index of barium carbonate allows the addition of barium carbonate to ceramic tile raw materials to effectively enhance the whiteness and glossiness of tiles, presenting a whiter and brighter appearance and meeting people's pursuit of aesthetics.
