Handling Notes

1. Elastomer bonding is recommended for this material, due to some of its characteristics not amenable to sputtering like brittleness, low thermal conductivity, etc.

Chemical Elements


Indium is a chemical element originated from the Latin ‘indicium’, meaning violet or indigo. It was first mentioned in 1863 and observed by F. Reich and T. Richter. The isolation was later accomplished and announced by T. Richter. “In” is the canonical chemical symbol of indium. Its atomic number in the periodic table of elements is 49 with location at Period 5 and Group 13, belonging to the p-block. The relative atomic mass of indium is 114.818(3) Dalton, the number in the brackets indicating the uncertainty.

Indium compounds are evaporated under vacuum to form thin films in the production of electronics and photovoltaic cells. Pure indium is utilized as a film layer in semiconductors.
