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.

We also offer other customized shapes and sizes of the sputtering targets, please send us an inquiry for more information.
Indium is also used to make other electrical components such as rectifiers, thermistors and photoconductors. Indium can be used to make mirrors that are as reflective as silver mirrors but do not tarnish as quickly. Indium is also used to make low melting alloys. An alloy of 24% indium and 76% gallium is a liquid at room temperature.
The indium sputtering target is used to coat the bearings of high speed motors since it allows for the even distribution of lubricating oil. Indium targets are also used for thin film deposition, decoration, semiconductor, display, LED and photovoltaic devices, functional coating as nicely as other optical information storage space industry, glass coating industry like car glass and architectural glass, optical communication, etc.
Elastomer bonding is recommended for the indium sputtering target. Stanford Advanced Materials is devoted to machining standard backing plates and working together with the Taiwan Bonding Company for providing bonding services.
