Gadolinium Metal
chemical element: Gd
( granular )
Ultra pure quantities of the element Gadolinium (atomic number 64), ideal for element collectors of those conducting experiments/producing alloys with pure Gadolinium metal. It has the highest thermal neutron capture cross-section of any known element. Gadolinium becomes superconductive below a critical temperature of 1.083 K. It is strongly magnetic at room temperature, and exhibits ferromagnetic properties below room temperature. Gadolinium metal is used as an emergency shut-down measure in some types of nuclear reactors.
