Overview
Anhydrous lithium hydroxide contains about 28.98 wt% lithium, higher than the monohydrate. It is mainly used for saponification of lithium-based greases, CO₂ absorbents in submarines and aerospace, ceramics and glass, and battery material synthesis where low moisture is required.
- LiOH ≥ 99.0%
- High lithium content per unit mass
- Granule or powder form
