Gallium is a chemical element with atomic number 31. It belongs to the group of light metals and denoted by the symbol “Ga”. Gallium in pure form not found in nature, but its compounds in very small amounts in bauxite and zinc ores.
Gallium is a soft ductile metal of silver color. At low temperatures is in the solid state, but melts at a temperature, not much more than room (29,8°C). In the video below you can see how the spoon out of gallium melts in a Cup of hot tea.
Since the element in 1875 until the semiconductor era, gallium is mainly used to create low melting alloys.
Currently, all gallium is used in microelectronics.
Gallium arsenide, the main connection element, which is used in microwave circuits, and infrared applications.
