They are rare earths a group of 17 chemical elements with tongue-tying names such as yttrium and thulium that are used in televisions cell phones laptops cars cancer treatment drugs nuclear reactor shielding aircraft engines and weapons. The uses for rare earths are as diverse as they are important.
The Geopolitics Of Rare Earth Elements
Rare earth metals a group of 17 chemical elements in the Earths crust are crucial to keeping our society running smoothlyand to transitioning to a clean-tech-driven economy.
Rare earth elements are important. The REEs ionic radii decrease on progression from La to Lu which results in a slight but predictable change in their chemical affinity. Rare earth is a group of elements that are not commonly found and difficult to extract. A total of 17 metals are included in this category.
But theyre not all bad. As the market corrects to. In this post we see the importance of Rare Earth Elements and their strategic significance.
Rare earth elements are crucial to the technology around us - theyre in phones computers tvs and hybrid cars. The others are heavy rare earth elements HREEs including europium terbium dysprosium and yttrium. Geoscience Australia update in response to COVID-19.
Rare earth elements are an essential part of many high-tech devices. Rare earths seem to be essential in the production of mobile phones electronics and medical equipment and a scarcity might affect the worldwide market and potentially help mitigate financial instability. The rare earths are a relatively abundant group of elements which range in crustal abundance from cerium at 60 parts per million to lutetium at 05 parts per million.
Rare earth is used in the manufacturing of important parts in electronic devices. Rare earth elements REEs which are needed for the manufacture of cell phones wind turbines and e lectric vehicles have risen in importance as demand for electronics and electric vehicles continues to increase. They are critical to high-performance optics and lasers and essential to the most powerful magnets and superconductors in the world.
Among these neodymium is extensively used in the. Rare earths are simply more expensive to mine than most metals when not mined with environmentally harmful chemicals. The latter isnt really an REE but its associated with them.
The global demand for rare earth elements has increased significantly in line with their expansion into high-end technology environment and economic areas. It plays the role of vitamin in modern industry and produces huge radiant economic benefits. Any why are they.
Rare earth elements REEs are a small but incredibly powerful family of metals that have an integral role to play in the manufacture of a multitude of modern electronic devices. The rare earth elements are essential for a diverse and expanding array of high-technology applications which constitute an important part of the industrial economy of the United States. Rare-earth elements are also critical to the push for clean energy and are instrumental in the design of eco-friendlier wind turbines and electric vehicles.
The elements are used to produce smartphones digital cameras flat-screen TVs computer hard disks LED. Rare Earth Oxides are used in mature markets such as catalysts glassmaking and metallurgy which account for 59 of the total worldwide consumption of rare earth elements and in newer high-growth markets such as battery alloys ceramics and permanent magnets which account for 41 of the total worldwide consumption of rare earth elements. Rare Earth Elements REE are metals having many similar properties.
Coveted for their magnetic and conductive properties they make technologies faster stronger lighter and more efficient. The rare earth elements REEs are commonly defined as lanthanum La and the 14 elements comprising the Lanthanide series. Rare earth elements REs are a set of 17 elements including the 15 lanthanides plus scandium and yttrium which have unique and widespread applications in magnetism photoluminescence catalysts lasers and among others.
Rare earth metals are actually not as rare as their name might imply. Why are they so important. Long-term shortage or unavailability of REE would force significant changes in many technological aspects of American society.
Geological Survey news release Going Critical explains. Furthermore rare earths are important for. Rare earths are widely used in aviation aerospace electronic information steel non-ferrous metals machinery manufacturing petrochemical and other industries.
However individual REs exhibit different intrinsic properties in optics electrics magnetism or catalysis so the separation and purification of RE concentrates are necessary for their. Although the dosage is small the effect is significant. Some of them are neodymium lanthanum europium scandium yttrium.
However Europium may also occur as Eu 2 and Cerium may occur as Ce 4. The REEs typically exhibit trivalent oxidation states. The unique magnetic electrochemical and luminescent properties of REEs are being put to work in all manner of electronic applications - from smartphones hard disk.
Rare-earth elements REE are necessary components of more than 200 products across a wide range of applications especially high-tech consumer products such as cellular telephones computer hard drives electric and hybrid vehicles and flat-screen monitors and televisions.
