Gallium is hard and brittle at low temperatures but melts as soon as it exceeds room temperature, it is soluble in acids and bases, slightly soluble in mercury, and very corrosive. Gallium is stable in dry air, the surface will generate oxide film to prevent further oxidation, but in humid air will lose its luster. Gallium's freezing point is very low, from the liquid state into a solid state, an expansion rate of 3.1%, should be stored in plastic containers.

Application

Gallium metal is mainly used in the preparation of gallium arsenide (GaAs), gallium phosphide (GaP), MO source for wireless communications, LED, etc. It is also the main raw material of the third-generation semiconductor gallium nitride (GaN), it can also be used for EPI gallium arsenide wafers, solar cells CIGS, the production of low-temperature alloys, gallium-indium-tin alloys, thermal conductivity medium, and high-temperature vacuum pumps. Gallium metal can also be used in permanent magnets Nd-Fe-B and other advanced magnetic materials.
