What is a Barium sulfate (BaSO₄)?

Barium sulfate (BaSO₄) is an inorganic compound composed of barium and sulfate ions. It appears as a colorless or white crystalline solid or powder and is characterized by its very low solubility in water and most organic solvents. While it is practically insoluble, it may dissolve slightly in strong acids or bases. Barium sulfate has wide applications in the medical field, especially as a contrast agent in X-ray imaging. It is commonly used in gastrointestinal X-ray procedures, where a barium-containing liquid is ingested to highlight internal organs like the stomach and intestines, aiding in the diagnosis of various conditions.

In addition, barium sulfate is used in the manufacture of paints, rubber, and plastics. Adding it to these materials improves their weather resistance and wear resistance, enhancing the quality of the final products. However, barium sulfate is toxic, and improper ingestion or excessive exposure can have serious health effects. Therefore, proper handling and precautions are essential when working with this compound.
