Product Description
Lanthanum-Cerium Metal (Misch Metal)
1. Basic Information
- Chinese Name: Lanthanum-Cerium Metal, Mixed Rare Earth Metal
- English Name: Lanthanum-Cerium Master Alloy, Misch Metal
- Chemical Formula: Ce-La (typical ratio La:Ce ≈ 35:65)
- CAS No.: 62379-61-7
- Molecular Weight: Approximately 139.5
- Appearance: Silver-gray metal in blocks, ingots or granules, with metallic luster and soft texture
2. Physical and Chemical Properties
- Density: Approximately 6.67 g/cm³
- Melting Point: Approximately 660–790℃ (varies with composition)
- Chemical Activity: Highly active, prone to oxidation and darkening in air, with faster oxidation in humid environments
- Solubility: Soluble in dilute acids (hydrochloric acid, sulfuric acid, nitric acid); reacts slowly with water to release hydrogen gas
- Storage: Must be kept sealed, dry, oil-immersed or wax-coated to isolate from air
3. Preparation Method
Molten Salt Electrolysis (Main Industrial Method)
- Raw material: Mixed rare earth chlorides (LaCl₃, CeCl₃)
- Process: In a high-temperature electrolytic cell, electrolyze molten rare earth chlorides to deposit lanthanum-cerium alloy at the cathode
Metallothermic Reduction Method
- Raw material: Rare earth fluorides + calcium metal
- Process: Reduce rare earth fluorides with calcium metal at high temperature to obtain the alloy
4. Main Applications
-
Metallurgical Additive (Steel Purifier)Deoxidizes, desulfurizes and removes harmful impurities, improving the toughness, ductility and heat resistance of steel.
-
Hydrogen Storage Alloy (Ni-MH Batteries)Prepares AB₅-type hydrogen storage alloys (such as LaNi₅ system) for the negative electrode of nickel-metal hydride batteries, widely used in hybrid vehicles and energy storage.
-
Non-Ferrous Metal AlloysStrengthens magnesium/aluminum alloys: refines grains, enhances strength, heat resistance and corrosion resistance.
-
OthersUsed in the production of flints, rare earth permanent magnet materials, special welding electrodes and reducing agents.
5. Safety and Storage
- Safety: Irritating; its powder is flammable. Avoid inhalation of dust and skin contact.
- Storage: Keep sealed, dry and in a cool place, or immerse in kerosene.
Lanthanum Cerium Metal
Chemical Formula: La+Ce
Application: Used as an additive for steel and non-ferrous metals, and as a hydrogen storage matrix material.
