Gadolinium Metal Gd CAS 7440-54-2 For Magnetic Refrigeration Additive
Name: Gadolinium metal Molecular formula: Gd
CAS: 7440-54-2 Molecular weight: 157.25
Description: Gadolinium an be made into various forms: Gadolinium Foil, Gadolinium block, Gadolinium sheet, Gadolinium powder. Gadolinium darkens in the humid air, and soluble in acid, insoluble in water. Gadolinium has the highest thermal neutron capture surface, which can be used as reactor control material and protection material. Ultra-low temperature near absolute zero can be obtained by magnetizing and cooling gadolinium salt.
