Lithium Hydroxide Monohydrate CAS 1310-66-3

What is Lithium Hydroxide Monohydrate CAS 1310-66-3?

Lithium hydroxide monohydrate CAS 1310-66-3 has the molecular formula LiOH·H₂O and a molar mass of about 41.96 g/mol. It forms small, colorless or white crystals, is hygroscopic, and reacts with carbon dioxide in the air. Its pH in a 1 M aqueous solution is around 14.

Specifications

Features

• Strong Alkalinity — As a strong base, it neutralizes acids efficiently and can be used in pH control.
• Hygroscopic Nature — It readily absorbs moisture (and CO₂) from the air, which means it must be stored carefully.
• High Solubility in Water — It dissolves in water to produce a clear, strongly alkaline solution (solubility ~109 g/L @ 20 °C).
• Thermal Stability — It has a relatively high melting point (~462 °C), which provides stability under many process conditions.
• Corrosive / Reactive — It reacts exothermically with acids and certain metals (e.g., aluminum, zinc), which is important for handling and reaction design.
• Intermediate for Lithium Compounds — It acts as a precursor in synthesizing a variety of lithium salts (e.g., lithium fluoride, lithium chloride), making it versatile in lithium chemistry.

Applications

• Battery Industry: Used in the production of lithium-ion battery materials (e.g., as a precursor to lithium salts).
• Grease Manufacturing: A key raw material in lithium-based greases, which are valued for high temperature stability and mechanical strength.
• Glass and Ceramics: Employed as a flux in glass and ceramics to adjust melting behavior and physical properties.
• Chemical Synthesis: Used to make other lithium compounds like lithium fluoride, lithium bromide, and lithium iodide.
• Alkalinity Agent: Utilized in processes that require strong bases, such as pH stabilization or chemical neutralization.
