INDIUM

Indium

Indium is a chemical element with symbol In and atomic number 49. This rare, very soft, malleable and easily fusible poor heavy metal is chemically similar to gallium and thallium, and shows intermediate properties between these two. Indium was discovered in 1863 and named for the indigo blue line in its spectrum that was the first indication of its existence in zinc ores, as a new and unknown element. The metal was first isolated in the following year. Zinc ores continue to be the primary source of indium, where it is found in compound form. Very rarely the element can be found as grains of native metal, but these are not of commercial importance.
