Key Takeaways: List of Rare Earth Elements. The rare earth elements (REEs) or rare earth metals (REMs) are a group of metals found within the same ores and possessing similar chemical properties. Scientists and engineers disagree on exactly which element should be included in a list of the rare earths, but they generally include the fifteen ...
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
From the lustrous sheen of rhodium to the high-strength resilience of scandium, these metals represent the pinnacle of scientific intrigue and industrial necessity. From the depths of the Earth’s crust to the far reaches of outer space, these metals captivate the imagination and drive the relentless pursuit of scientific discovery and innovation.
Rare-earth element, any member of the group of chemical 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 metals are actually not as rare as their name might imply. They are critical to high-performance optics and lasers, and essential to the most powerful magnets and superconductors in the world.
The rare earth elements are a group of transition metals, found mainly in the first row below the periodic table (the lanthanide series), plus scandium and yttrium. Despite the name, these elements are fairly abundant in the Earth’s crust.
Rare Earth Elements (REE) are becoming increasingly important in electronic devices used in the defense, alternative energy, and communications industries. Minable deposits of REEs are found in only a few locations.
Rare earth elements (REEs), which comprise of only 17 elements from the entire periodic table, play a critical role to our national security, energy independence, environmental future, and economic growth.
Statistics and information on the worldwide supply of, demand for, and flow of the mineral commodity group rare earths - scandium, yttrium, and the lanthanides. The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays.
Despite their name, rare earth elements (with the exception of the radioactive promethium) are relatively plentiful in the Earth's crust. The more abundant REE are each similar in crustal concentration to commonplace industrial metals such as chromium, nickel, copper, or lead (Figure 2).
