Indium Metal 99.995% 4N5 has risen dramatically demand for liquid crystal displays, flat panel and plasma displays, touch screens, low melting point metal alloys, LED light, photovoltaic field, wet glass production and as a coating for bearings or other parts etc.
Indium Foil is available in many sizes in sheet form to be a choice for thermal interface material with some cool characteristics, and also ideal for creating cryogenic vacuum seals, and also used in nuclear reactors to help control the nuclear fission reaction by absorbing some of the neutrons.
Indium Shot or indium ball with tear drop shaped of 1-5mm diameter can be used to prepare melts for casting, extrusion or doping and thermal evaporation coating for its high surface area as compared to ingot.
Indium Wire is widely used to create high vacuum seals in cryogenic apparatus and for special lead-free indium solders
