You had it all doped out.

Rare earth mines are found throughout the world.

Selects the color of the rare earth elements

So, in 2000 we wrote Rare Earth. In 2003, we then asked,

There are two series of rare earth metals, the lanthanides and the actinides.

Well, Rare Earth actually taught me an awful lot about meeting the public.

Helium 3 very rare on the surface of the Earth, very common in space.

For example, the first working laser was a ruby laser, made from ruby (chromium doped corundum).

Indeed, rare earth elements are rare only in the sense that they are distributed in small quantities and must be extracted from ores, a time consuming process.

So, in 2000 we wrote Rare Earth. In 2003, we then asked, let's not think about where Earths are in space, but how long has Earth been Earth?

The design uses 192 beamlines in a parallel system of flashlamp pumped, neodymium doped phosphate glass lasers.

China dominates the global market simply because it has fairly abundant rare earth ores close to the surface.

Rare.

Extremely rare.

It's rare.

Beauty rare

Rare boy, he And rare boys, we

It's rare that history comes with a man that his fear is set in the hearts of kings all around earth.

They could not yet produce pure samples of all the rare earth elements, even in the form of their salts, and in some cases they were unable to distinguish between mixtures of two very similar (adjacent) rare earth elements from the nearby pure metals in the Periodic Table.

Filter Out Rare

They're very rare.

It's very rare.

That's become rare.

A rare meeting.

Rare, hungry birds.

The rare earth threat is not confined to Japan, as China accounts for over 90 of the world s production, roughly 120,000 tons.

Carl Sagan and Frank Drake, for instance, could well be considered pluralists while proponents of the Rare Earth hypothesis are modern skeptics.

Also, the method of separating the rare earth elements by the method of ion exchange had not been invented yet in Moseley's time.

These rocks have low concentrations of large ion lithophile elements (LILE), light rare earth elements (LREE), volatile elements and other highly incompatible elements.

Brave leadership is rare.

A rare Persian Leopard.

This is very rare.

These instances are rare.

It's a rare condition.

It's a rare thing.

If something is rare, or perceive rare, you can sell it for a profit.

And India s government has shown its political savvy by forging an agreement to provide Japan with rare earth minerals a vital component in many manufacturing processes after China chose to use its supplies of rare earths as a diplomatic stick.

Other countries might worry about the health risk to workers in rare earth processing, but that does not appear to be true of China.

Rare earth elements change through time in small quantities (ppm, parts per million), so their proportion can be used for geochronology and dating fossils.

Political violence has been rare.

These are not rare occurrences.
