Through atomization, Advanced Refractory Metals can produce indium powder with D50 around 10-15 um. Besides, we can offer Indium powder with a different particle size as requested, such as -325 meshes, -500 meshes, -600 meshes, etc.

Indium powder is mainly used in the production of solar cell conductive paste, ITO conductive film, welding materials, low melting point alloys, seals, etc.
Pure Indium metal applications:
-Thin films to form lubricated layers
-Making particularly low melting point alloys (e.g. an alloy of 24% indium-76% gallium is liquid at room temperature)
-Thermal interface material
-Control rods for nuclear reactors, typically in alloy of 80% silver, 15% indium and 5% cadmium
Our Indium Powder is carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
