Indium

Indium metal has played a key role in technology advances since it was first investigated by Dr. William S. Murray in 1924 in Utica, NY, and with the creation of the Indium Corporation in 1934, the two have been tied together, leading, and supporting the advancement of technologies that we all rely on today.

Indium metal is extracted primarily from indium-bearing zinc or tin ores and purified to various grades utilizing state-of-the-art statistical process controlled refining technologies.

Indium Corporation produces and refines indium in the USA, Korea, and China.

Gallium

Gallium

Gallium is a by-product of aluminum extracted during the processing of bauxite into alumina. It can also occasionally be found in Zn ore. We are a refiner and supplier of gallium materials.

Indium Corporation supplies gallium:

  • In the form of shot and ingot
  • In the form of sputtering targets, after being alloyed with other elements (Cu-Ga, Cu-In-Ga)
  • In the form of compounds, such as Anhydrous Gallium Trichloride or Gallium Sesquioxide
Germanium

Germanium

Germanium is extracted from germanium bearing zinc ores or from certain coal ores, collecting the flue dusts after the burning process. It can occasionally be found in copper ores. We refine germanium at our facility in the USA.

Typical Impurities (ppm)
Indium Corporation has the production capability to deliver levels of up to 99.999%-pure (5N) tin. Testing is available upon request for specific impurities.

Tin

Indium Corporation is the world’s premier supplier of pure tin and tin alloys and compounds. With a melting point of 505.08 K (231.93°C or 449.47°F) as well as its corrosion-resistant nature, tin is becoming increasingly popular for a number of new and innovative applications, including aerospace and semiconductor.

Products for Laser and Optical Packaging

Gold

Indium Corporation is a leading joining and bonding materials innovator for medical, aerospace, optoelectronics, and automotive applications. When even 10 ppm of contamination can cause process and application failures – quality counts. Indium Corporation casts our alloys, which enables us to closely control the process from start to finish and ensure purity.

High Purity Indium

High purity indium: Indium Corporation is the leading global supplier of commercial indium; high-purity indium; and indium fabrications, alloys, and compounds. Indium metal is extracted from indium-bearing ore and is refined to various grades in high volume utilizing state-of-the-art SPC-controlled refining technologies. Rigorous quality standards and advanced analytical instrumentation such as ICP and GDMS ensures consistent product quality from lot-to-lot.
