Barium sulfate is a radiographic contrast agent that is supplied as white to lightly colored powder for suspension (40% w/w) for oral administration. It has a molecular weight of 233.4 g/mol and a density of 4.5 g/cm3. Formulations contain excipients including: artificial candied sugar flavor, carrageenan, citric acid, ethyl vanillin, natural and artificial orange flavor, polysorbate 80, saccharin sodium, simethicone, sodium citrate, sodium carboxymethylcellulose, sorbitol and xanthan gum.
Uses
Primary
- WHO LEM radiocontrast agent
Other
- Precursor to barium sulfide, thence to all barium salts
Natural occurrence
- The mineral barite is primarily barium sulfate
Hazards
- GRAS
Production
Extraction
Synthesis
- A metathesis reaction between barium sulfide and sodium or potassium sulfate in water
- BaS(aq) + Na2SO4(aq) → BaSO4(s) + Na2S(aq)
