Description

Gallium is a medium-density, soft metal with a very low melting point and a high boiling point. This particular property keeps gallium in liquid state in a wide range of temperatures, making it suitable to be used as a thermometric material for high temperature thermometers. Its melting point, as well as its triple point, are used as reference temperatures, which make gallium a perfect choice to calibrate thermometers. The rest of the applications of gallium are not of gallium metal, but of different gallium compounds such as gallium arsenide and nitride, which are semiconducting materials widely used in both the electronics industry and the led lighting industry, producing blue and violate LEDs as well as diode lasers.
