It is a soft, silvery-white metal that is liquid near room temperature.
It is not found as a free element and is only present in small quantities in certain minerals, such as zinc ores and bauxite.
Gallium is used to make gallium arsenide, which is a core substrate for semiconductors.
It is utilized in the production of semiconductor wafers, integrated circuits, mobile and satellite communications (in chipsets), and LEDs (in displays).
Gallium also finds applications in automotive and lighting industries, as well as in sensors for avionic, space, and defense systems.
It joins Cs, Rb, and Hg as a non-radioactive metal near room-temperature as well as Si, Ge, Bi, and Pu as elements whose liquid forms are denser than their solid forms.
