General description

Indium,a rare and stable element, exhibits exceptional properties such as high thermaland electrical conductivity. It finds application in diverse alloys, batteryproduction, and the synthesis of indium tin oxide, essential for transparentelectrodes in LCDs and touchscreens. Additionally, Indium is utilized in theproduction of solar cells, LEDs, and other optoelectronic devices.

Application


  • Indium-containing semiconductors: Discusses the role of indium in semiconductor technology, relevant for both academia and material science, focusing on its application in indium-tin oxide and other indium compounds (Schwarz‐Schampera, 2014).

  • Recovery of indium from liquid crystal displays: This article presents methods for the recovery of indium from waste electronics, an area of significant interest for sustainable chemistry and materials science (Rocchetti et al., 2016).

  • The oxidation and surface speciation of indium and indium oxides exposed to atmospheric oxidants: Explores the chemical properties and reactions of indium in various oxidation states, relevant to environmental and materials chemistry (Detweiler et al., 2016).
