Aplikasi

     Indium has semiconductor uses in transistors, thermistors and photoconductors. It is also used to make low-temperature alloys; for example, an alloy of 24% indium-76% gallium is liquid at room temperature. Indium can also be plated on to metal and evaporated on to glass to give a mirror with better resistance to corrosion than silver. A tiny long-lived indium battery has been devised to power new electronic watches.

Bahan Baku

Indium is a chemical element with symbol In and atomic number 49. This rare, very soft, malleable and easily fusible poor 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 (free) metal, but these are not of commercial importance.
