The article looks at the governmental restrictions, mining efforts, and the possible alternatives to rare earth metals (REMs) in China and the U.S. According to International Union of Pure and Applied Chemistry (IUPAC), they are also called rare earth elements and consist of 15 elements such ...
Light rare earth elements include the metals ranging from lanthanum to gadolinium on the periodic table of elements, while heavy rare earth metals range from terbium to lutetium. So-called green technologies often depend upon rare earth elements. For instance, Toyota uses an estimated 7,500 tons ...
China also said it is imposing export controls on rare earth metals such as tungsten, tellurium, ruthenium, molybdenum and ruthenium-related items - the country controls much of the world's supply of such metals, which are critical for the transition to clean energy. ...

Are there metals far scarcer than iridium and enormously more expensive than gold — while at the same time, non-radioactive or very, very nearly so? As it happens, yes. A line of radioactive cosmetics introduced in 1930 Each element comes in varieties called isotopes whose atoms differ in...
Today’s electronics, in every form, rely on a variety of mined rare earth metals and precious metals. Neodymium, dysprosium and terbium, for example, are essential in the production of powerful magnets used in speakers, electric motors and hard disk drives. Europium and yttrium are used in ...
Rare earth metals are a series of chemical elements that are found in the earths crust (Rare Earth Tech. Alliace), and, because of their unique are used in a variety of different technologies, including computers, mobile phones, transport (cars, motorbikes, buses) and for defence purposes (...
What is the most abundant metal in the Earth's crust? Aluminum is the most abundant metal in the Earth's crust, although it's never found in its pure form naturally due to its reactivity. 6 What are rare earth metals used for? Rare earth metals are used in high-tech applications, inc...
