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