Overview
Lanthanum chloride solution is an inorganic compound derived from lanthanum, a rare-earth metal. It is primarily used in industrial and research settings due to its unique chemical properties. The solution form is preferred for applications requiring easy handling and precise dosing. Lanthanum chloride is highly soluble in water, making it suitable for aqueous processes. Its hygroscopic nature necessitates careful storage to prevent moisture absorption. The compound is often utilized in catalytic systems and as a precursor for other lanthanum-based materials.
Physical and Chemical Properties
Lanthanum chloride solution appears as a clear, colorless to slightly yellow liquid. It is highly soluble in water and exhibits hygroscopic properties, meaning it readily absorbs moisture from the air. The solution is typically stable under normal conditions but may react with strong oxidizing agents. The molecular weight of lanthanum chloride (LaCl₃) is 245.26 g/mol, and its density is approximately 1.42 g/cm³ at 20°C. The solution does not have a defined melting or boiling point, as these properties depend on the solvent concentration.
Main Applications
Lanthanum chloride solution is widely used in the production of optical glasses and phosphors, where it enhances light transmission and luminescence. It also serves as a catalyst in organic synthesis and petroleum refining. In water treatment, lanthanum chloride is employed to remove phosphates, which can cause algal blooms. Additionally, it is a valuable reagent in research laboratories for studying rare-earth chemistry and developing new materials.
Safety and Storage
Lanthanum chloride solution is corrosive and can cause skin and eye irritation. Proper personal protective equipment (PPE), such as gloves and goggles, should be worn when handling the solution. In case of contact, rinse immediately with plenty of water. Store the solution in a cool, dry place in tightly sealed containers to prevent moisture absorption and contamination. Avoid exposure to strong oxidizing agents, as this may lead to hazardous reactions.
B2B Procurement Guide
When procuring lanthanum chloride solution, verify the concentration and purity specifications to ensure they meet your application requirements. Bulk orders may offer cost advantages, but storage conditions must be carefully managed. Suppliers should provide detailed safety data sheets (SDS) and certificates of analysis (CoA). Consider the packaging options, such as plastic or glass bottles, based on the volume and handling needs. Lead times and logistics should also be factored into procurement planning.
