#49, Indium, In: The name derives from indicum, the Latin word for indigo, refering to a bright blue line seen in its emission spectrum (the element was discovered using emission spectroscopy).
Indium’s most widespread use is in the compound indium (III) oxide in solid solution with tin (IV) oxide, together named indium tin oxide. Indium tin oxide is useful for electrodes in LCDs (liquid crystal displays) and capacitive touchscreen panels because it is fairly transparent when it is made thin. While visibly transparent, indium tin oxide reflects infrared well, and so is useful to coat glass for windows and low pressure sodium lamps, and doors on refrigerators and ovens.
Indium is also an ingredient in some solders and a few semiconductor compounds (such as indium arsenide for infrared detectors).
