Barium Sulfate (BaSO4)

Barium sulfate (BaSO4) is a chemical compound made of barium, sulfur, and oxygen. It's a white, powdery substance that is mainly used in the medical field as a contrast agent for X-rays and CT scans. When patients swallow or receive it in an enema, it helps highlight their gastrointestinal tract for clearer imaging. Barium sulfate is also used in paints, plastics, and as a filler in various products due to its brightness and opacity. It is generally safe for use in these applications, though it is not soluble in water or other liquids, which means it doesn't easily mix.
