Some main functions and uses of gallium are electronic and semiconductor industries, thermometers and thermostats, adhesives and casting alloys, reagents in chemical laboratories, medical imaging, alloy additives and so on.

1. Electronics and semiconductor industry

Gallium has important applications in electronics and semiconductor industry. Can be used for manufacturing high-frequency electronic devices, diodes, photoelectric elements, solar cells and lasers.

2. Thermometers and thermostats

Gallium is often used as an element in thermometers and thermostats because its characteristics can be accurately measured in different temperature ranges.

3. Adhesives and casting alloys

Gallium has a low melting point, so it can be used to make special alloys and adhesives. It is usually used in high temperature applications, welding agents and aluminum alloy manufacturing.

4. Reagents in the chemical laboratory

In some chemical laboratories, gallium can be used as a reagent for some chemical reactions or analysis.

5. Medical imaging

Gallium can be combined with some radioisotopes for nuclear medical imaging.

6. Alloy additives

Gallium can be added to some metal alloys to change their properties and characteristics, such as improving the corrosion resistance and ductility of the alloys.
