Erbium Metal Powder Er CAS 7440-52-0 For Cemented Carbide Additive

Erbium powder, as a rare earth element material, has unique physical and chemical properties. It has a dark brown color, but it oxidizes easily in the air, so it needs to be kept sealed to avoid humidity and high temperatures.
In special metallurgy, the metal erbium powder as an additive can significantly improve the properties of the material. At the same time, it is also an important raw material in the manufacture of cemented carbide and non-ferrous metals, as well as a component of hydrogen storage matrix materials. In addition, the metal erbium powder can also be used as a reducing agent for the production of other metals, and it also plays an important role in the atomic energy industry and the electronics industry.

Name: Erbium metal powder, Erbium powder

Molecular formula: Er

CAS: 7440-52-0

Molecular weight: 167.26

Description

Erbium metal can be prepared by reduction of anhydrous erbium fluoride with calcium metal. Erbium metal is introduced into hydrogen to absorb hydrogen to obtain brittle erbium hydride solid. Then, erbium metal powder can be obtained by dehydrogenation at vacuummed and high temperature.
