Gallium is a silvery, glass-like, soft metal. It sits close to the non-metals in the periodic table and its metallic properties aren’t as obviously metallic as most other metals. Solid gallium is brittle and is a poorer electrical conductor than lead.
Gallium readily alloys with most metals, and is used as an ingredient in low-melting alloys.
Low melting gallium alloys are used in some medical thermometers as non-toxic substitutes for mercury.
Gallium arsenide is used in semiconductor production mainly for laser diodes, light-emitting diodes and solar panels. It is also used to create brilliant mirrors.
Extremely high-purity (>99.9999%) gallium is commercially available to serve the semiconductor industry.
Gallium is used for neutrino (A neutrino is a fermion that interacts only via the weak subatomic force and gravity) detection.
