Nezve Gadolinium
Gadolinium is a silvery-white, malleable metal with the highest thermal neutron capture of any known element. It is ferromagnetic near room temperature and used in MRI contrast agents.
Mashandisiro & Maapplication
MRI contrast agents, neutron radiography, nuclear reactor shielding, uye magnetorefrigerant alloys.
