Storare:	Storing in sealed, dry and cool condition, not exposing to air for long time, avoiding moisture.
Characteristics:	As-cast dark gray 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.
