Gallium has a very low melting point; it starts melting in hand.
The element gallium possesses some properties for a heat-transfer liquid. In addition, its addition, it is a unique material, having a low melting point and a high boiling point. Pure gallium melts at 29.78°C, and suitable alloying will produce a metal that melts below room temperature.
- Pure gallium is not a harmful substance for humans to touch
- Gallium is a soft, silvery metal used primarily in electronic circuits, semiconductors and light-emitting diodes (LEDs).
- Gallium remains in the liquid phase over a temperature range of about 2,000 °C
