Rare earth magnets, like that of Neodymium-iron-boron, are used in sensors, and even ferrite magnets contain small amounts of rare earths and minor metals like Lanthanum and Cobalt to improve magnet performance by as much as 25%. GPS navigation, touch screens, power windows, and all the hi...
The U.S. used to be a top manufacturer of rare earth metals back in the 1960s, but eight years ago environmental infractions shut down the Mountain Pass, California mine, the largest deposit of rare earth metals outside of China. Currently, there are efforts to restart production at the ...
But rare-earth magnets, on the other hand, are produced with alloy metals that offer a stronger, more intense magnetic field. To learn more about this manufacturing marvel and the applications in which it is used, keep reading. Strength of Rare-Earth Magnets So, just how strong is a rare...

Space Station, but some experts think more people could one day work and even live in space.20 People could one day mine other planets and asteroids(小行星) for materials such as rare earth metals.This could reduce the environmental bad effect caused by mining for these resources on Earth. ...
Rare earth metals exhibit rich and widely investigated magnetic behavior in the bulk. Comprehensive reviews are offered by Elliott (1972), Coqblin (1977) and Jenson and Mackintosh (1991). The 4f core electrons remain distinct from the conduction states and couple according to Hund's rules to ...
The world's rarest precious metals — also the heaviest! Hassium might be twice as heavy as iridium and osmium. Element 164, eka-darmstadtium, may be even heavier.
focused on strategies for ensuring the supply of five rare earth metals identified by the government as critical. “We used to have cell phones where you could snap out the battery, which is probably the biggest single target for recycling. With smartphones, those things are built so you can...
especially suitable for production with special The required complex iron parts are widely used in machinery manufacturing such as automobiles, tractors and diesel engines; rare earth metals are added to non-ferrous alloys such as magnesium, aluminum, copper, zinc and nickel to improve the mechanical...
