Electric motors are simple, with just a handful of critical components. For mechanical reasons, a housing is required; it’s called a stator because it stays put. A rotor is needed to spin a shaft and create torque. To make the motor work, the stator and the rotor need to interact magnetically so as to convert electrical energy to mechanical energy. Two rare earth elements, neodymium (Nd) and praseodymium (Pr), are the key raw materials in ultra-strong permanent magnets, which are essential to the electronics, technology, automotive and electric motor industries.NdPr Oxide is a key component in...

Source:Idaho State JournalIn light of the aggression made by a Chinese warship toward a U.S. Navy vessel last month, one might question the wisdom of the U.S.’s dependency on China for 71 percent of its rare earth minerals (REMs). According to a recent summary report by the U.S. Geological Survey, the U.S. produces only 24 percent of the REMs it needs to produce many of its manufacturing necessities. Rare earth minerals are used in the production of fertilizers for agriculture, high-tech and green energy products, oil refining processes, and the production of military equipment.The USGS conduc...

Source:phys.orgAmericans use rare earth elements (REEs) every day—without knowing it. In fact, they are crucial to society. Rick Honaker, professor of mining engineering at the University of Kentucky, knows all about these fascinating elements and the modern electronics they make possible.REEs are a series of 17 chemical elements found in the Earth's crust. "On a periodic table, they are typically the lanthanide series, which is the horizontal row at the bottom of the periodic table, plus scandium and yttrium. All of those elements are extremely important for everyday applications,&qu...
