4 Rare Earth Elements That Will Only Get More Important

Online, July 24, 2012 (Newswire.com) - Rare earth elements-a set of 17 related metals, mostly shunted off to a tacked-on lower line of the periodic table-are crucial to the way we live now; Charles Braizer Global Markets sheds some light into these metals.

"Rare earth" stuck, but the elements themselves turned out to be pretty common, mixed in small concentrations into rock the world over.

Lanthanum, first discovered in 1893, is a great example of this. There's more lanthanum on this planet than silver or lead and it's the second most abundant rare earth element, but there weren't a lot of uses for it in the early days. Today, every Prius hybrid car on the road carries with it about 10 pounds of lanthanum. And yet, most Prius owners don't even know they use this rare earth element every day. A big breakthrough in battery technology, nickel-lanthanum hydride batteries pack more power into a smaller space

Europium was the first isolated, high purity rare earth element to enter the public marketplace, in 1967, as a source of the color red in TV sets. There had been color TV before europium, but the color quality was weak. Today, as cathode ray tube TVs go the way of the dodo, europium is more likely to turn up in white LED-based lights, which could someday be an energy efficient replacement for both incandescent and compact fluorescent bulbs.

The applications of erbium are deeply important: add a little erbium to the optical fibers that carry data in the form of light pulses, and those pulses get amplified. It can also be used as part of the gain medium that amplifies light in a laser. When you do this, you end up with a laser that can be used for dental surgery and skin treatments because it doesn't build up much heat in the human skin it's pointed at.

In the late '70s, Sony introduced the Walkman, a (relatively) small, (relatively) portable music player. Why were they able to shrink the form factor? Magnets. Specifically, magnets made from the rare earth element samarium, which were smaller and stronger than anything then available. Today, the samarium-based magnets have largely been replaced by magnets made with neodymium, which are even smaller and even stronger. We have these magnets to thank for the miniaturization of gadgetry. But they're also responsible for making necessarily chunky tech lighter and cheaper-like the turbines that turn wind into electricity, and the drills that search for oil deep below the surface of the Earth.
