About Ga

gallium

Gallium is a chemical element with symbol Ga and atomic number 31. Gallium is a soft, silvery metal, and elemental gallium is a brittle solid at low temperatures. If it is held in the human hand long enough, gallium will melt, since it melts at the temperature of about 29.76 °C (85.57 °F) (slightly above room temperature). The melting point of gallium is used as a temperature reference point. The alloy galinstan (68.5% gallium, 21.5% indium, and 10% tin) has an even lower melting point of −19 °C (−2 °F), well below the freezing point of water.
Today, nearly all gallium is used in electronics. Gallium arsenide, the primary chemical compound of gallium in electronics, is used in microwave circuits, high-speed switching circuits, and infrared circuits. Gallium nitride and indium gallium nitride, minority semiconductor uses, produce blue and violet light-emitting diodes (LEDs) and diode lasers.
