Indium is prepared from the dust residues of zinc processing. It forms trivalent compounds and some monovalent ones. Indium is used in solders, low-melting-point alloys, germanium transistors, glass seals, bearing alloys, and (combined with group VA elements) in semiconductors. atomic number 49 relative atomic mass 114.8 relative density 7.31 (20°C) melting point 156.6°C (313.9°F) boiling point 2,072°C (3,762°F) Related category    • INORGANIC CHEMISTRY Also on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History Transport Concepts & Designs (partner site) BACK TO TOP
