| Gadolinium is never found in nature in elemental form. It is obtained from many rare minerals such as bastnasite, monazite and trace amounts in gadolinite. |
|
| Uses |
| Phosphors in colour TV tubes and in the manufacture of compact discs and computer memory. Gallium Gadolinium Garnet (Gd3Ga5O12) is a material with good optical properties, and is used in fabrication of various optical components and as substrate material for magneto-optical films. |

| Notes |
| Gadolinium becomes superconductive below a critical temperature of 1.083 K (-272.067'C). Strongly magnetic at room temperature. |
