· Around 73% of rare earth elements are used in mature industries, including glass, ceramics and metallurgy. The remaining 27% are used in the production of neomagnets, which are essential components in electric vehicles (EVs). Using the force produced when two magnets with opposing poles repel each other, electric motors use permanent magnets and coils that have been .
· A team of researchers from the University of Exeter in the United Kingdom have discovered a new hypothesis to predict where rare earth elements neodymium and dysprosium can be found.
The rare earths are a set of 17 elements that share similar properties and are usually found together in geological deposits, requiring advanced metallurgical processing to recover and separate. They consist of the 15 lanthanide elements on the periodic table, along with scandium and yttrium. The most abundant rare earths are lanthanum, cerium and neodymium, all considered light rare earths ...
RareEarth Elements provide the building blocks to produce the best magnets in the world. When you think magnets, you likely think of the one on your fridge that hold up your kids' or grandkids' pictures and artwork. Those aren't the magnets I'm talking about. The most important type of magnet is called a "permanent magnet." There are permanent magnets in your cell phone and in MRI ...
· Rare earth elements (REE) include the lanthanide series elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. Currently these metals have become very critical to several modern technologies ranging from cell phones and televisions to LED light bulbs and wind turbines. This article summarizes the occurrence of these metals in the Earth's crust, their ...
· Rare Earth Elements: The Technology Metals. In the midst of our daily hustle and bustle, we often don't notice the raw materials that go into the technologies we rely on. Rare earth metals, also known as rare earth elements or simply "rare earths", are one such group of raw materials. From this group of 17 minerals, many are found in a range of technologies—from our smartphones and ...
· The aim of this paper is to develop an analytical method for quantitative determination of rare earth elements in scheelite via LAICPMS using REEdoped tungstate single crystals as calibration standards. For this purpose, three REEdoped tungstate single crystals (, Dy:NaGd(WO 4) 2, Yb:NaGd(WO 4) 2, and Nd:NaGd(WO 4) 2) were obtained, the homogeneity of REE distribution and .
