Technical Grade Lithium Hydroxide (LiOH), typically supplied as lithium hydroxide monohydrate (LiOH·H₂O), is an inorganic alkaline compound with purity levels ranging from 95% to 98%. This grade is widely used in industrial, chemical, and metallurgical applications where ultra-high battery-grade purity is not required.
Technical grade LiOH provides a cost-effective solution for large-volume processing while maintaining strong alkalinity, high solubility, and predictable chemical performance.

Advantages of Technical Grade LiOH
✔ Cost-effective compared to battery-grade lithium hydroxide
✔ Suitable for large-volume industrial use
✔ Reliable and well-understood chemical behavior
✔ Easily convertible into other lithium compounds
✔ Stable global supply for chemical and lubricant industries
Why Choose Technical Grade (95–98%)
Technical grade lithium hydroxide is the preferred choice for non-battery applications where purity requirements are lower, but chemical performance, availability, and cost efficiency are critical. It is extensively used in grease manufacturing, glass and ceramic processing, metallurgical operations, and bulk chemical production.
