Cerium Misch Metal

Specification:-


  • La: 30-40 % , Ce : 60-70% (50 gms / 500 gms)


 

Mischmetal is a German word that means a mix of metals. The first mischmetal was created from monazite ore. Mischmetal is a rare earth alloy that is composed of cerium, lanthanum, neodymium, praseodymium and other rare-earth metals in different proportions. Other than rare-earth metals, mischmetal also contains impurities. In special applications, impurities, like Fe is are intentionally added with a motive to improve the properties. It can be availed in different forms, for instance rod, chunks and ingot.

Synonyms:

Misch metal, cerium mischmetal, flint mischmetal, rare earth mischmetal, mixed metal



Physical Properties:

This is a soft and brittle rare earth alloy that is not available in its pure form. Though it is possible to get 99.99% purity. The toughness, ductility, strength and conductivity properties tend to change due to the lattice defects and microstructural inclusions created by the impurities.


Mischmetal Applications:

The country that is regarded as the largest producer of rare earths, including mischmetal alloy is China. Some major industrial applications of mischmetal are as follows:


  • It is used in the manufacturing of vacuum tube as an oxygen getter.
  • It is used in metal hydride technology-based batteries.
  • It is used as a spark source for initializing fires and flames.
  • It is used for improving castability and mechanical properties in several alloys by manufacturers of steel and non-ferrous metals.
  • It is used as an alloying additive in ductile iron foundry.
