In the realm of ceramics, barium carbonate (CAS 513-77-9) is a highly valued additive, primarily recognized for its functions as a flux in glazes and its effectiveness in preventing scumming in clay bodies. These properties make it indispensable for producing high-quality ceramic ware, tiles, and bricks.

As a flux, barium carbonate plays a critical role in ceramic glazes. It effectively lowers the melting point of the glaze mixture, allowing it to flow smoothly and evenly over the ceramic surface during firing. This process, known as vitrification, leads to a durable, glossy, and impermeable finish. Barium carbonate is particularly noted for its ability to produce desirable matte finishes, adding aesthetic appeal to various ceramic products. Manufacturers often seek out barium carbonate to achieve specific textural and visual effects in their glazes, which might be difficult to attain with other additives.

Beyond its role in glazes, barium carbonate is a highly effective solution for combating scumming in bricks and tiles. Scumming is a common issue where soluble salts present in the clay migrate to the surface during drying and firing, forming an unsightly white, chalky residue. Barium carbonate neutralizes these soluble sulfates by reacting with them to form insoluble barium sulfate and calcium carbonate. This chemical interaction effectively locks the salts within the clay body, preventing them from reaching the surface and thus ensuring a clean, uniform finish on the final ceramic products. This application is vital for maintaining the aesthetic quality and structural integrity of bricks and tiles.

The consistent supply and quality of barium carbonate are crucial for ceramic manufacturers. NINGBO INNO PHARMCHEM CO.,LTD. offers high-purity barium carbonate that meets the demanding standards of the ceramics industry, ensuring reliable performance in both glaze formulations and scum prevention strategies. Whether you're looking to buy barium carbonate for its fluxing capabilities or its anti-scumming properties, understanding its application benefits is key to achieving optimal ceramic production results.
