Gallium is widely used in the electronics industry, especially in semiconductor materials. It is a key component in gallium arsenide (GaAs) and gallium nitride (GaN), which are used in high-speed integrated circuits, microwave frequency devices, and optoelectronic components like LEDs and laser diodes. These materials are essential in mobile phones, satellite communications, and wireless transmission systems due to their ability to operate at high frequencies and temperatures. In renewable energy, gallium is used in high-efficiency photovoltaic cells, particularly in multi-junction solar cells for space and concentrated solar power applications. Its compounds improve the conversion efficiency of sunlight into electricity. Gallium also has applications in medical imaging and cancer treatment. Radioactive gallium compounds, such as gallium-67 and gallium-68, are used as radiotracers in nuclear medicine to detect tumors, inflammation, and infections through imaging techniques like SPECT and PET scans. Due to its low melting point and high boiling point, gallium is used in high-temperature thermometers and as a heat-transfer medium in certain industrial processes. It serves as a non-toxic alternative to mercury in some applications. Additionally, gallium is being explored in the development of flexible electronics and liquid metal alloys for soft robotics and wearable technology.
