Use
The most important use of gallium is as a doping agent for semiconductors, transistors, and other solid state devices. It is used to produce semiconducting compounds. Miscellaneous important semiconductor applications include magnetic field sensing, temperature sensing, and voltage amplification. Some gallium compounds, such as gallium arsenide, gallium phosphide, and magnesium gallate have major applications in electroluminescent light emission, microwave generation, and UV activated powder phosphors. Another important use of gallium in oxide form involves spectroscopic analysis of uranium oxide. Gallium also is used to make many low melting alloys. Some other uses for gallium are in high-temperature thermometers as a thermometric fluid; in high vacuum systems as a liquid sealant; as a heat-transfer medium; and to produce mirrors on glass surfaces.
