Indium Sulfide (In2S3)
Indium sulfide (In2S3) is an orange-red to red colored powder with the sulfuric odor that is characteristic to all sulfides. It is insoluble in water and most organic solvents but decomposes in common mineral acids, releasing hydrogen sulfide gas.
Indium sulfide is primarily used as a buffer layer in copper-indium-gallium-diselenide (CIGS) photovoltaic solar cells, where it replaces the toxic material cadmium sulfide. Indium sulfide is available in 4N and 5N degrees of purity, and as a powder or compressed pellets.

Indium Corporation manufactures 60 different alloys that contain indium, in addition to over 150 other non-indium-bearing alloys, such as SAC and SnPb.
Having samples of different alloys can be very useful for R&D departments. Fortunately, Indium Corporation offers solder research kits so you can test various alloys with your assembly process to find just the right match.
Indium alloys can help you by reducing the assembly temperature needed to form interconnections. (solder joints)
