Description and Uses

Gallium is the 32nd most abundant element and constitutes 0.0005% of the Earth’s crust. It is found most commonly in association with zinc, germanium, and aluminum and is found primarily in the mineral germanite. Gallium(III) is the primary oxidation state for gallium compounds; its chemistry resembles that of aluminum(III).

Gallium and gallium compounds have numerous uses in optoelectronics (e.g., LEDs), telecommunication, aerospace, and many commercial and household items, for example, alloys, computers, and DVDs. In addition, gallium is used in special high-temperature thermometers, in place of mercury, and in arc lamps.
Medically, gallium alloys are used in dental prostheses, radioactive gallium has been used to locate bone lesions, and nonradioactive gallium has been used as an antitumor agent. Gallium has been used experimentally as an adjunct to cisplatinum cancer chemotherapy. It has also been used to treat hypercalcemia and inhibit bone resorption. Gallium maltolate is under development as a treatment for Paget’s disease.
