Molycorp produces high purity gallium metal for metallurgical, chemical electronic, and compound semiconductor applications in the following grades:
- 4N (99.99%) gallium for metallurgical, chemical and solar applications
- 6N (99.9999%) and 7N (99.99999%) gallium for electronic and compound semiconductor applications
- MBE grade (99.999999%) for molecular beam epitaxy applications
In addition to high purity gallium, Molycorp manufactures gallium nitrate that is produced from 4N gallium. Primary gallium production takes place at our Stade, Germany facility. Secondary gallium production takes place at both of our Blanding, Utah and Peterborough, Canada operations.
Gallium is a widely distributed element associated with many other minerals. Since it is not found in concentrated deposits, it is rarely mined directly. Gallium is primarily obtained as a by-product in the recovery of other metals such as zinc and aluminum.
Its chemical behavior is similar to aluminum. In general there is a thin oxide coating on the surface.
It is stable against water, but can react vigorously with halogens (even at low temperatures) and other strong oxidants and bases. With its very low melting point and high boiling point, gallium has the widest liquid range of any element. It also has a strong tendency to supercool below its freezing point.

Gallium Nitrate solutions are available in various concentrations. The solution can be packaged in 500 mL bottles, 55 gallon drums, and 275 gallon bulk containers according to the quantity ordered. Current production capacity is over 1,000 kg of contained Gallium in solution per month.
Our Gallium Nitrate is produced from 4N pure Gallium.
Gallium Nitrate is a custom product and as such the specifications vary depending upon specific customer requirements.

Indium was discovered in 1863 by Reich and Richter, and was named indium as a reminder of the characteristic indigo blue color of its spectrum.
Indium does not occur in the native stage in nature. It is present in trace moments in many lead-, tin-, and zinc-bearing ores, from which it can be recovered as a by-product. It is a shiny, very malleable and ductile metal that melts at 156.6 degrees Celsius. Indium is not attacked in moist air, but dissolves in acid. It forms compounds with selenium, tellurium, antimony, and arsenic.
Indium was first used for the manufacturing of bearings for aircraft engines. It is a component of low-melting-point alloys, but its main usage presently is as indium oxide and indium-tin oxide (ITO) applied to glass as a conducting layer in optical-electronic devices (flat screens). High-purity indium (6N and above) has found applications in electronics, such as the InP single crystal.
