Gadolinium Metal Powder Gd CAS 7440-54-2 For Magnetic Refrigeration Additive

Metallic gadolinium powder, a form of the rare earth element gadolinium, has a silvery white luster and excellent ductility. Its melting point is as high as 1313°C and boiling point is as high as 3266°C, showing excellent high temperature resistance.
In industrial applications, metal gadolinium powder is favored for its unique physical and chemical properties. It is often used as an additive in specialty steels and specialty alloys to significantly improve the strength and corrosion resistance of the material. At the same time, in the electronics industry, metal gadolinium powder also plays an important role in the preparation of electronic components such as capacitors and resistors to ensure the stable operation of equipment.
In addition, metal gadolinium powder is also widely used in scientific research, magnetic materials, refractories and medical fields. On the medical side, gadolinium compounds such as the complex of gadolinium - diethylenediamine pentaacetic acid (DTPA) are used as contrast agents in magnetic resonance imaging (MRI) to aid in the diagnosis of diseases.

products features

Name: Gadolinium metal powder, Gadolinium powder

Molecular formula: Gd

CAS: 7440-54-2

Molecular weight: 157.25

Description

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