Particle Size: | 1-5um, 5-10um, -325mesh, -200mesh, -100mesh. | ||
Memo | Can custom-made as per request. |
Storare: | Storing in sealed, dry and cool condition, not exposing to air for long time, avoiding moisture. |
Characteristics: | Black powder is extremely susceptible to oxidation and ignition in the air. |
Application: | 1. Lanthanum metal is an important raw material for the production of hydrogen storage alloys for nickel-metal hydride batteries. It can also be used to produce other pure rare earth metals and special alloys. |
2. Adding a small amount of lanthanum to the steel can improve its ductility, impact resistance and ductility. | |
3. A small amount of lanthanum is present in many swimming pool products to remove phosphate-feeding algae. | |
4. Lanthanum metal can be further processed into various shapes of ingots, blocks, wires, foils, plates, rods, disks and powders. |
