Barium sulfate is a radiographic contrast agent that is supplied as white to lightly colored powder for suspension (40% w/w) for oral administration. Formulations can 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
WARNING: Like calcium sulfate, this is a "terminal chemical". Producing this compound at scale for any purpose is a bad idea, logistically. Every mol of sulfate ions trapped in this material is one mol of sulfuric acid lost.
Extraction
Synthesis
- Combining any soluble barium salt (e.g. barium chloride) with any soluble sulfate salt (e.g. sodium sulfate or copper sulfate) will yield a precipitate of barium sulfate.
Extraction
- Naturally occurring barite is primarily barium sulfate/
