Detail

Asal nama Latin: indicum (color indigo), the color it shows in a spectroscope.
Negara penemuan Germany
Penemu Ferdinand Reich, T. Richter

Indium is a soft, silvery post-transition metal in group 13. It is chemically related to gallium and thallium, but its stable chemistry is dominated by the +3 oxidation state, with +1 compounds also known. The element is rare in Earth's crust and is obtained chiefly as a by-product of zinc refining. Its technological importance is disproportionate to its abundance, especially because transparent conducting indium tin oxide is central to flat-panel displays, touch screens, and other optoelectronic devices.

Indium is available in ultra pure form. Indium is a very soft, silvery-white metal with a brilliant luster. The pure metal gives a high-pitched "cry" when bent. It wets glass, as does gallium.

The name derives from the term "indigo" for the indigo-blue line in the element's spark spectrum. It was discovered in 1863 by the German physicist Ferdinand Reich and the German metallurgist Hieronymus Theodor Richter, while examining zinc blende. They isolated indium in 1867.

Indium was discovered by the German chemists Ferdinand Reich and Hieronymus Theodor Richter in 1863. Reich and Richter had been looking for traces of the element thallium in samples of zinc ores. A brilliant indigo line in the sample's spectrum revealed the existence of indium. Indium is about as abundant as silver but is much easier to recover since it typically occurs along with zinc, iron, lead and copper ores.

From the brilliant indigo line in its spectrum. Discovered by Reich and Richter, who later isolated the metal. Until 1924, a gram or so constituted the world's supply of this element in isolated form. It is probably about as abundant as silver. About 4 million troy ounces of indium are now produced annually in the Free World. Canada is presently producing more than 1,000,000 troy ounces annually.
