Overview
Lithium sulfate is the leach product from sulfate processing of spodumene and lepidolite; after purification and concentration it can be converted to lithium carbonate or hydroxide. It is also used in glass, ceramics and pharmaceuticals.
- Li₂SO₄ ≥ 99.0%
- Highly water-soluble and easy to purify
- Available as solid or solution
