Product Overview
Lithium hydroxide, anhydrous (98% purity) is a highly reactive alkaline compound valued for its strong basicity and hygroscopic nature. This white crystalline powder is synthesized through the reaction of lithium carbonate with calcium hydroxide, ensuring minimal impurities for consistent lab performance. Its high solubility in water (12.8 g/100 mL at 20°C) makes it ideal for aqueous solutions, while its thermal stability (melting point: 462°C) allows for high-temperature applications. The reagent’s low molecular weight (23.95 g/mol) and density (1.43 g/cm³) facilitate precise volumetric measurements in analytical procedures. As a non-volatile solid, it avoids the handling risks associated with liquid bases while maintaining comparable reactivity. The anhydrous form eliminates water content, preventing unwanted side reactions in moisture-sensitive processes. Its CAS number (1310-65-2) and UN classification (corrosive solid, Class 8) underscore the need for proper storage in airtight containers away from acids and organic materials. The product’s 98% assay guarantee ensures reliable stoichiometry in chemical syntheses, particularly in lithium-ion battery research and gas purification systems.
FAQs
1. Can this lithium hydroxide be used for CO₂ absorption in closed systems?
Yes, the anhydrous form is highly effective for CO₂ scrubbing due to its strong basicity and lack of bound water, which prevents carbonation before reaction.
2. What precautions are needed when handling this powder?
Always wear nitrile gloves, safety goggles, and work in a fume hood, as the powder is corrosive to skin and mucous membranes upon contact.
3. How does this compare to lithium hydroxide monohydrate for battery applications?
The anhydrous form offers higher lithium content per gram (58.7% vs. 41.3% in monohydrate), reducing weight in electrolyte formulations.
4. What’s the shelf life under proper storage conditions?
When stored in a sealed container with desiccant at room temperature, the product remains stable for 24 months without significant degradation.
5. Is this suitable for preparing lithium greases or lubricants?
While chemically possible, industrial-grade lithium hydroxide with higher particle consistency is typically preferred for lubricant manufacturing.
