The rare earth elements (REEs) are a group of seventeen chemical elements on the periodic table: scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium. The rare earths exhibit unique chemical properties that make them highly valued in a wide variety of appliions ...

rareearths with 1,2diaminocyclohexaneN,N,N1,N'1etraacetic acid (DCTA), where only the 1:1 chelate is formed, were studied as examples of strong complexes. The separation of large amounts of pure rareearths and yttrium by ion exchange was developed recently at Ames Laboratory (1,2,3) and has increased the availability of pure rare earths ...

rare earth elements has burgeoned, especially in lowcarbon technologies, and demand for them has grown rapidly – a trend which is expected to continue. At the same time, there is international concern about the security of their future supply, their costs, and the impacts this might have. In light of this increased interest, the Geological Society has decided to produce this briefing note ...

· Collectively, these metals are also called rare earth elements (REEs). In comparison with many other elements, however, the rare earths are not really rare, except for promethium, which has only radioactive isotopes. Yttrium, lanthanum, cerium, and neodymium are all more abundant than lead in the earth's crust. All except promethium, which probably does not occur in nature, are more abundant ...

RareEarth Elements (REEs) are a group of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium is found in most rare earth element deposits and is sometimes classified as a rare earth element. The International Union of Pure and Applied Chemistry include scandium in their rare earth element definition. Rarely, a ...

The rare earths form an especially interesting group of elements in the periodic table. For the most part they have three electrons in the valence shell or conduction band, and as the atomic number increases the inner l|f shell is gradually filled up. The existence of an unfilled k£ shell leads to many interesting features in the electric and magnetic properties of these metals. In particular ...

Rare Earth Elements (REEs) are becoming increasingly integrated in new technologies, especially within the clean energy, military, and consumer electronics sectors. As each of these sectors continues to grow, so does the industry's demand for the constituent REEs.

· The 'rare earth elements' (REEs) are a series of similar elements that are rarely encountered on the Earth's surface. They're not even allowed to sit in the proper periodic table, banished to a small row floating below with only the 'actinide series' (the what?!) for company. REEs have always been the lonely kid in the playground, but now our mum is making us invite them to our ...
