Uses
Other
- Chlorination catalyst antimony pentachloride
- Component of WHO LEM medicines sodium stibogluconate and Meglumine antimoniate
- Alloying material with lead for batteries, bearings.
- Pharm: potassium antimonyl tartrate is a (relatively) safe emetic
Natural occurrence
- Does (very rarely) occur naturally as native metal.
- Primary ore is Stibnite
Hazards
Production
Extraction
The primary ore of antimony is Stibnite, Sb2S3.
roast/reduce
Stibnite, roasted in air, converts to antimony trioxide, which can be carbothermically reduced.
binary salt
It is possible to directly reduce stibnite to antimony in a molten salt bath [1]
