Lanthanum Metal

Product Description:


1.Name : Lanthanum Metal

2.Appearance: gray metal block

3.Formula: La

4.Formula weight: 138.91

5.CAS No.: 7439-91-0

6. EINECS No.: 231-099-0

7.Density: 6.19 g/cm3

8. Melting point: 920°C



Applications:


1. The metal lanthanum shell is used in the production of nickel-metal hydride batteries.


2. For the production of other pure rare earth metals and special alloys. Adding small amounts of lanthanum to steel improves its ductility, impact resistance and ductility.


3. Manufacture of ceramic capacitors, piezoelectric ceramic dopants and X-ray luminescent materials such as lanthanum oxybromide powder.


4. It is used in rocket fuel, reducing agent and automotive catalytic converter, such as catalyzing the oxidation reaction of carbon monoxide when doped with cadmium oxide, and catalyzing the hydrogenation of carbon monoxide to form methane when doped with palladium. 

Lanthanum oxide impregnated with lithium oxide or zirconium oxide (1%) can be used to make ferrite magnets. It is a very efficient selective catalyst for the oxidative coupling of methane to ethane and ethylene.

 It is used to improve the temperature dependence and dielectric properties of barium titanate (BaTiO3) and strontium titanate (SrTiO3) ferroelectrics, and to manufacture fiber optics and optical glass.


5. Lanthanum-138 is radioactive with a half-life of 1.1×1011 years and has been tried to treat cancer.
