Sources |
Found throughout the crust in minerals like bauxite, germanite and coal, but does not exist in pure form in nature. |
|
Uses |
Used in semiconductor production, quartz thermometers, laser diodes, used to locate tumors and for creating mirrors. 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. It has been suggested that a liquid gallium-tin alloy could be used to cool computer chips in place of water. As it conducts heat approximately 65 times better than water it makes a considerably better coolant. |

Notes |
Gallium, along with caesium and mercury, is one of the few metals that are liquid at (or near) room temperature. |
Some sources suggest that it may cause dermatitis from prolonged exposure; other tests have not caused a positive reaction. It will however stain your skin if you hold it in your bare hands. |
