Formation of Barium Sulfate
BaO + SO3 → BaSO4
Overview
Barium oxide combines with sulfur trioxide to form barium sulfate, an extremely insoluble white compound. Barium sulfate is used extensively in medical imaging as a contrast agent because it is opaque to X-rays and non-toxic when ingested.

Everyday Example
Patients drink a barium sulfate suspension (barium meal) before gastrointestinal X-ray examinations to visualize the digestive tract.
Industrial Importance
Barium sulfate is used as a filler in paints, plastics, and rubber, as a weighting agent in drilling fluids, and as a radiocontrast agent in medical imaging.
