dysprosium

This is just MIC specific, there's also stuff like dysprosium for highend capacitators where PRC has functionally 100% control, i.e.

It requires blasting to extract from the bastnasite and is low in heavy rare earths such as Dysprosium and Terbium.

Instead of selling the refined neodymium & dysprosium for $50, they want to sell the electric motors that sell for $1,000.

S is going to take the dysprosium from China by force.

Europium and Dysprosium are common for greens & blues.

(Apparently Dysprosium is also mainly mined in China.) The argument usually heard for reducing reliance on rare-earth metals is the political one.

If this is a pre-war economy, the US is screwed not because of AI but because we started a stupid trade war that's going to cut us off of our supply of dysprosium which is critical for defense manufacturing.

Lynas Rare Earths noted in it's last quarterly report that it has started it's HRE separation circuit and will begin producing Dysprosium this month (May 2025), followed by Terbium in June at it's Malaysian site.

Even ten to fifteen years ago the effort German automakers put into saving a milligram Dysprosium here and there - not only in the drive motor but every electric motor in the vehicle - was insane.

More recently, I've noticed dysprosium being added to the mix as well, though TBH I've never noticed any difference in brightness or duration compared to stuff I could get ten years ago.

Why are rhenium, rhodium, lanthanum, europium, dysprosium, thulium, ytterbium, yttrium, strontium, thallium, magnesium and manganese so irreplacable?

Electric motor materials include aluminum, cobalt, copper, iron, silicon-steel, manganese, graphite, lithium, and a variety of rare-earth minerals (dysprosium, neodymium, niobium, terbium and praseodymium).

An old TRS-80 assembly programming book I had suggested that an early conference of computer experts suggested that the last six digits be named actinium, barium, curium, dysprosium, erbium, and fermium until "cooler heads prevailed".

It is worth noting, however, that Mountain Pass primarily produces "light" rare earths, while the mines in southern China will remain the predominant source of several "heavy" rare earth metals for several years to come (e.g., dysprosium).

Summary: An announcement by a Stanford University team in Physical Review Letters that it has created the world's first dipolar quantum fermionic gas from the metal dysprosium—"an entirely new form of quantum matter," as Stanford applied physics professor and lead author Benjamin Lev put it—represents a major step toward understanding the behavior of these systems of particles.

Please refer to my comment on Dysprosium's post for my answer on this.

Dysprosium has a high value per kilogram but the current annual demand for all rare earth elements combined is under $8 billion, compared to e.g.

Lithium sure, but not a number of other REEs like Neodymium, Dysprosium, Molybdenum, and others are only found in unequally distributed concentrated deposits.
