31 Ga Gallium

Metal, mass: 69.723 u, 2 stable isotopes (69, 71). Abundance rank (earth/space): 38/31

Click image to magnify. Ultrapure gallium, transition from liquid to solid (crystalline). Original size in cm: 1 x 2 and 1 x 4
Crystallizing gallium Crystallizing gallium, too
Gallium is a soft, silvery metal, which is increasingly used in high tech industry. Notable here is gallium arsenide, an important semiconductor for special applications. Pure gallium already melts at 30°C (86°F). It is relatively safe to handle, but eye contact and longer skin contact should be avoided.

Solid gallium Solid gallium after some time
Solid gallium, fresh and after some time (2 months) at room temperature. The gallium spiral melted a bit and merged with another piece, which was stored in the same box.

Blue LEDs
Blue LEDs in front of a white painted wall. Those use gallium nitride or indium gallium nitride as semiconductor.
