Gallium is widely used in the electronics industry, especially in semiconductors. It is a key component in compounds like gallium arsenide (GaAs) and gallium nitride (GaN), which are used to make high-speed integrated circuits, light-emitting diodes (LEDs), and solar cells. These materials are essential in smartphones, satellite communications, and fiber-optic systems due to their ability to convert electricity into light efficiently. Gallium is also used in thermal management applications because it has a low melting point and high boiling point, making it suitable for high-temperature thermometers and as a liquid metal coolant in some advanced systems. Additionally, it serves in medical imaging and cancer treatment, where radioactive gallium isotopes help detect tumors and inflammation in the body. Due to its ability to wet glass and ceramics, gallium is used in some specialized mirrors and optical coatings. It is also being explored in flexible electronics and liquid metal alloys for soft robotics and wearable technology.
