Indium is a post-transition metal with properties similar to gallium. It is soft and metallic-gray in color. It has a density of 7.3 g/cc, a melting point of 157°C, and a vapor pressure of 10-4 Torr at 742°C. One of its notable characteristics is its ability to cling to glass and other similar surfaces. 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.

Vacuum evaporation means the evaporation materials are evaporated to atoms or molecules in vacuum by current heating, electron beam heating and laser heating. Atoms or molecules make rectilinear motion to impact substrate surface and condense to form films.
