Uses
Justification Questioned
Other
- Essential material of WHO LEM component lithium carbonate
- Essential material of some voltaic cell technologies
Natural Occurrence
- Elemental lithium does not occur naturally
- Mineral sources include spodumene, lepidolite, and petalite, amblygonite
- Some natural brines contain high concentrations of lithium in dissolved lithium compounds such as lithium carbonate
Hazards
Production
Extraction
Electrolysis
- Electrolysis of a molten mixture of lithium chloride and potassium chloride. At a 45:55 ratio, they melt at 300°C. In the presence of oxygen and moisture in the air, the lithium will react.
- 45 Li{55 KCl(s)45 Li(l) + 45 Cl(g)300°C, 9v}→
- 45 Li
