1864 Lyell Inaug. Addr. in Reader 17 Sept. 358 A fourth metal named indium, from its indigo-coloured band, was detected by Professor Richter of Freiberg in Saxony in a zinc ore of the Hartz.

1874 tr. E. Lommel Nature of Light (ed. 4) 114 The blue light of Indium undergoes a still stronger refraction than that of Thallium.

1882 Nature No. 639. 290 He finds that indium is like some other metals in not coming under the often-accepted rule that pure metals have a change of coefficient of resistance with temperature.

Compounds

attributive, as indium bromide (In Br), indium chloride, indium monochloride (In Cl), indium dichloride (In Cl₂), indium trichloride (In Cl₃); indium iodide, indium oxide, indium hydroxide; indium salts, etc.
