| gallium |
CAS Number: 7440-55-3. Gallium is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures, which makes possible its use in high-temperature thermometers. Ultra-pure gallium has a beautiful, silvery appearance. Gallium compounds are also used to create semiconductors and microwave equipment. Chemical formula = Ga. Molecular weight = 69.72 g/mol.

| gallium |
Gallium is not produced in the United States, and demand is satisfied by imports, primarily high-purity material from France and low-purity material from Kazakhstan and Russia. More than 95% of gallium consumed in the United States is in the form of gallium arsenide (GaAs). Analog integrated circuits are the largest application for gallium, with optoelectronic devices [mostly laser diodes and light-emitting diodes] as the second largest end use.
