Indium definition
A soft, malleable, silvery-white metallic element found primarily in ores of zinc and tin, used in making fusible alloys, in plating aircraft bearings and mirrors, and in compounds for making liquid crystal displays and transistors. Atomic number 49; atomic weight 114.82; melting point 156.60°C; boiling point 2,072°C; specific gravity 7.31; valence 1, 2, 3.
noun
A rare metallic chemical element, soft, ductile, and silver-white, occurring in some zinc ores and used in producing bearings and various alloys that melt at relatively low temperatures: symbol, In; at. no. 49
noun
A soft, malleable, silvery-white metallic element that occurs mainly in ores of zinc and lead. It is used in the manufacture of semiconductors, in bearings for aircraft engines, and as a plating over silver in mirrors. Atomic number 49; atomic weight 114.82; melting point 156.61°C; boiling point 2,080°C; specific gravity 7.31; valence 1, 2, 3.
A natural element that, combined with tin, is widely used as a transparent wire. Indium-tin-oxide (ITO) electrodes are attached to the glass plates that sandwich the liquid crystals in LCD displays. They are also used in OLED displays and solar cells. Indium is not mined directly, rather it is extracted from the refuse when zinc and other materials are refined. See LCD and OLED.
A metallic chemical element (symbol In) with an atomic number of 49.
