Description

Rare Earth Chlorides are a group of inorganic salts comprising the chlorides of the lanthanide series elements, a critical class of materials for modern high-tech industries. Their unique electronic and catalytic properties make them indispensable for manufacturing advanced materials with specialized optical, magnetic, and chemical characteristics. This product is essential for producers and R&D teams in the catalysis, electronics, and specialty glass sectors seeking reliable, high-purity raw materials.

Application

• Catalyst Manufacturing: Key precursors for petroleum cracking catalysts, automotive exhaust catalysts, and polymerization catalysts.
• Phosphors and Optical Materials: Used in the production of phosphors for LED lighting, display screens (LCD, PDP), and X-ray intensifying screens.
• Specialty Glass & Ceramics: Act as polishing compounds for optical glass and additives to control refractive index and impart color in specialty glasses.
• Magnet Production: Serve as starting materials in the synthesis of high-performance neodymium-iron-boron (NdFeB) and samarium-cobalt (SmCo) permanent magnets.
• Metallurgy: Used as alloying additives to improve the strength and workability of magnesium, aluminum, and other non-ferrous alloys.
• Water Treatment: Function as coagulant aids in wastewater treatment processes.
• Research & Development: Fundamental reagents in chemical synthesis and materials science research for developing new compounds and nanomaterials.

Quality Control

Our Rare Earth Chlorides are produced and tested under a stringent quality management system. Each batch is analyzed to ensure it meets precise compositional and purity specifications, typically focusing on total rare earth oxide (TREO) content and controlling specific impurity levels. Certificates of Analysis (COA) detailing assay, identity, and impurity profiles are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored in a cool, dry place with minimal exposure to ambient humidity. For long-term storage, consider using a desiccator or maintaining the container under an inert atmosphere. Store away from incompatible materials such as strong bases and oxidizing agents.
