Rare earth metals are not considered a good physical investment like precious metals, which hold low-tech intrinsic value. Rare Earth Metals and Their Applications In the periodic table of the elements, the third column lists the rare earth elements.
Rare-earth element, any member of the group of stone elements consisting of three elements in Group 3 (scandium [Sc], yttrium [Y], and lanthanum [La]) and the first extended row of elements below the main body of the periodic table (cerium [Ce] through lutetium [Lu]).
Rare Earth Elements End Use and Recyclability (Report), U.S. Geological Survey 2011 report on established and newer markets for rare earth elements. Describes in detail the quantities of specific rare earth elements used in different industries, and discusses prospects for future recycling.
We also serve as an authorized vendor to many defense contractors and renewable energy companies. Clark is a trusted name within all of these industries that rely upon rare earth elements to make safer, smaller, more effective equipment. We prioritize safety and quality, and we look forward to serving your rare earth element testing needs.
Rare earths: uses; Uses of rare earth elements; As rare earth elements are a group of 17 elements with many irreplaceable properties, rare earth metals can be widely used in many areas including magnets, catalysts, metal alloys, electronics, glass, ceramics, new materials and some other high-technology fields. As essential and functional materials, rare earth elements have been named "The
Oct 17, 2017· “Rare earth elements occur in ores in very small concentrations, a few thousand parts per million. Extensive processes of mining, grinding, extraction, and purification are needed to transform the ores to very high purity (approximately 99.9 percent minimum) rare earth metals required for commercial applications,” she said.
The rare earths trade dispute, between China on one side and several countries led by the US on the other, was over China's export restrictions on rare earth elements as well as tungsten and molybdenum, which are used to make many electronics. China controls 97% of the production of these elements.
As electrolysis can usually only be used in the preparation of general industrial rare earth metals, if high purity metal needs to be prepared, vacuum reduction will generally be the choice. This method can produce 13 kinds of single rare earth elements, the exceptions
Rare earth elements are essential for the production of numerous weapons in the U.S. arsenal, including Tomahawk cruise-missiles, smart bombs, Predator drones, electromagnetic railguns, laser weapons, the electric motors in Joint-Strike Fighters, radar, and submarine communications systems.
Since this rare-earth ion is part of the mix in most REE ores, contamination is less of a problem than if the retaining ion were not part of the mix. This section describes equipment and procedures used in conducting batch equilibrium tests and semicontinuous column tests.
