Rare earth metals

That might not seem like much, but when you add up the over million retired cell phones that live in desk drawers, closets, and shoeboxes, you start to get somewhere. This confusion led to several false claims of new elements, such as the mosandrium of J.

China capitalized on its dominant position and began restricting exports and allowing rare earth oxide prices to rise to historic levels. Yttrium or Y 39 Yttrium is a non-lanthanide rare earth element used in many vital applications, such as superconductors, powerful pulsed lasers, cancer treatment drugs, rheumatoid arthritis medicines, and surgical supplies.

Rare earth elements are peppered throughout your phone, from the glass display, making it harder, to magnets in speakers, headphones, and vibrating motors, making them more powerful despite their small size.

Those elements, from lanthanum on the left to lutetium on the right plus yttrium and scandium are called the rare earths. Uranium ores from Ontario have occasionally yielded yttrium as a byproduct. One way we can all contribute is by digging our old cell phones out of our desks.

It also has applications related to petroleum refining and positron emission tomography. Rare earth elements are heavily used in all of these industries, so the demand for them should remain high.

Europium, gadolinium, and terbium were either considered as a separate group of rare-earth elements the terbium groupor europium was included in the cerium group, and gadolinium and terbium were included in the yttrium group.

Gadolinium or Gd 64 Gadolinium has particular properties that make it especially suited for important functions, such as shielding in nuclear reactors and neutron radiography.

Nomenclature of Inorganic Chemistry. Similar compositions are found in xenotime or gadolinite. Headphones rely on magnets, often made of neodymium, to produce lots of sound from a small enclosure.

The United States was a significant producer through the s, but low-priced materials being sold by China forced mines in the United States and other countries out of operation.

The only concentrated sources of scandium currently known are in rare minerals such as thortveitite, euxenite, and gadolinite from Scandinavia and Madagascar. The exact number of rare-earth elements that existed was highly unclear, and a maximum number of 25 was estimated. There are 17 elements that are considered to be rare earth elements—15 elements in the lanthanide series and two additional elements that share similar chemical properties.

In they obtained a white oxide and called it ceria. Rare earths are ubiquitous in the consumer electronics industry, not just cell phones.

This effort has resulted in a decline in the amounts of rare earth materials used in some types of magnets and a shift from rare earth lighting products to light-emitting diode technology.

Rare-earth element

Other applications for lanthanum include wastewater treatment and petroleum refining. Despite their high relative abundance, rare-earth minerals are more difficult to mine and extract than equivalent sources of transition metals due in part to their similar chemical propertiesmaking the rare-earth elements relatively expensive.

For instance, cerium oxide is used as a catalyst in catalytic converters in automotive exhaust systems to reduce emissions, and is highly desirable for precision glass polishing.What Are Rare Earths?

Rare earths are a series of chemical elements found in the Earth’s crust that are vital to many modern technologies, including consumer electronics, computers and networks, communications, clean energy, advanced transportation, health care, environmental mitigation, national defense, and many others.

Apr 17,  · Rare earth metals are integral to a lot of modern technology, and China controls the vast majority of the world’s supply.

But is this really a problem? A new discovery of rare earth materials by. Cell phones and other gadgets are troves of rare earth elements, but unless people recycle their old electronics, we can't recover them. Rare Earth Elements (REE) are becoming increasingly important in electronic devices used in the defense, alternative energy, and communications industries.

Minable deposits of. Rare earth metals are actually not as rare as their name might imply. Critical to high-performance optics and lasers and key to the most powerful magnets and superconductors in the world, rare earths are simply more difficult to mine than most metals and generally don't accumulate into rich ores.
