Indium ( In - 156.1°c )

 

Indium is a very soft, silvery-white metal with a brilliant lustre, primarily produced as a by-product of zinc and lead smelting.
Indium is used to coat the bearings of high speed motors since it allows for the even distribution of lubricating oil. Indium is used to dope germanium to make transistors. It is also used to make other electrical components such as rectifiers, thermistors and photoconductors, and has a use in the production of flat screen TV's and computers displays. Also used to produce low melting alloys such as our Lens alloy117 and 136, Indium is very good at withstanding low temperature and this makes it useful for gaskets and seals in cryogenics.

Uses

Nearly 15% of Indium consumption goes in the manufacturing of electrical components.
Indium has a very low melting point and ability to conduct electricity, it is used in making of solders and alloys.
Indium also finds extensive use in coatings of glasses, aircraft windows, building windows, doors, refrigerators and ovens.
Indium tin oxide is popular in low pressure sodium lamps.
Indium is used as a solder alloy owing to its ability to fill the difference of the coefficient of thermal expansion (CTE) of two different metals that cause breakage between metal joints due to contraction and expansion.
