Indium Metal Sputtering Target High Purity In Target Vacuum Thin Film Technology

Product Specification

Indium sputtering targets are functional targets made from high-purity indium metal, appearing silvery-gray with a good metallic sheen. Its physical parameters include a melting point of 156.61°C, boiling point of 2060°C, and a density of 7.3 g/cm³. Indium is a typical soft metal, with low mechanical strength and is easily scratched by fingernails, but it has good plasticity and ductility, making it easy to process into various target shapes.

Indium targets are essential to vacuum thin-film technology, providing superior adhesion to glass and ceramic substrates. Utilizing evaporation or magnetron sputtering, they facilitate the deposition of uniform, high-density films for photovoltaics, touch panels, and semiconductor metallization. Indium remains a critical material for fabricating transparent conductive films (TCOs) and high-reliability electrode connections.
