Description
Gadolinium is a chemical element in the periodic table of elements, with symbol Gd and atomic number 64.
A silvery-white to grey-white lustrous rare earth metal, it is ductile and malleable. At temperatures above 1508 K, the densest spherical packing transforms into a body-centred cubic crystal structure.
In dry air, gadolinium is relatively stable; in humid air it forms an unprotective, loosely adhering and flaking oxide layer. It reacts slowly with water. It dissolves in dilute acids.
At 49000 Barn, gadolinium has the highest thermal neutron capture cross section of all known elements. Its high burn-out rate severely limits its use as a control rod in nuclear reactors.

* This is a recommendation based on our experience with these materials in our sputter guns. Rates are based on non-bonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or less depending on the material.
