Lanthanum Metal

Lanthanum metal is a pale gray, elastic rare earth metal that oxidizes immediately upon contact with air and reacts with water to form hydroxide. Lanthanum Metal is an essential raw material in producing Hydrogen Storage Alloys for NiMH batteries and is also used to produce other pure rare earth metals and specialty alloys. Small amounts of Lanthanum added to steel improves its malleability, impact resistance, and ductility. Small quantities of Lanthanum are present in many pool products to remove the phosphates that feed algae. Lanthanum Metal can be further processed into various shapes of ingots, pieces, wires, foils, slabs, rods, discs, and powder.

Lanthanum Metal Shapes

• Irregular pieces of approx 250g or 500g

• Bars in diameter from 12.7 mm (min. length 10 mm / approx. 7–10 g to the max. 120 mm / approx. 95–100 g)

• Wire with the minimum diameter of 2.3 mm

• Powder

Applications of Lanthanum Metal

1. Lanthanum-Nickel alloy is used to store hydrogen gas for use in hydrogen-powered vehicles.

2. Lanthanum is found in the anode of nickel-metal hydride batteries used in hybrid cars.

3. Lanthanum is used as a petroleum cracking catalyst, splitting long-chain hydrocarbons into shorter chained.

4. Lanthanum is used in making light vision goggles (infrared-absorbing glass).

5. Lanthanum oxide is contained in high-quality cameras and telescope lenses, making use of its high refractive index and low dispersion.

6. Lanthanum carbonate is used in reducing blood levels of phosphate in patients with kidney disease.

7. Lanthanum compounds are also used in some pool products to reduce the level of phosphate nutrients that algae feed.

8. Lanthanum’s small amount is added to steel to improve its malleability, resistance to impact, and ductility, whereas the addition of lanthanum to molybdenum decreases its hardness and sensitivity to temperature variations.

9. Lanthanum chloride is used in phosphor lamp coating.
