- Gallium (Ga) Metal Designations:
Chemical Name: Gallium
Chemical Formula: Ga
1) Gallium is grayish when solid; tin or silvery colored when molten. It has one of the longest liquid ranges of any metal, has a low vapor pressure even at high temperatures and shows a tendency to remain in a supercool state.
2) Gallium is one of four metals that can be molten at room temperature. It has a higher density as a liquid than as a solid. Gallium can be alloyed with most metals and is frequently used as such to reduce the melting point.
3) It is a soft metallic poor metal, elemental gallium is a brittle solid at low temperatures. As it liquefies slightly above room temperature, it will melt in the hand.

- Gallium (Ga) Metal Precautions:
While not considered toxic, the data about gallium are inconclusive. Some sources suggest that it may cause dermatitis from prolonged exposure; other tests have not caused a positive reaction. Like most metals, finely divided gallium loses its luster and powdered gallium appears gray. Thus, when gallium is handled with bare hands, the extremely fine dispersion of liquid gallium droplets, which results from wetting skin with the metal, may appear as a gray skin stain.
