Gallium is a metal which can be a liquid near room temperature, which makes it possible for use in high-temperature thermometers.
Gallium(III) oxide has been studied in the use of lasers, phosphors and luminescent materials and has been shown to demonstrate catalytic properties. Gallium has also been used as an insulating barrier in tight junctions. The stable oxide of gallium, monoclinic β-Ga2O3, has current applications as gas sensors and luminescent phosphors and can be applied to dielectric coatings for solar cells. This stable oxide has also shown potential for deep-ultraviolet transparent conductive oxides.
High purity (normally higher than 99.9995+%) Gallium compounds, such as Gallium oxide and Gallium Fluoride can be used in electrical components, such as Infrared detectors, high speed transistors and in photovoltaic devices.
