Comments on: Will We Cope If The Rare Earths Live Up To Their Name? https://www.techmetalsresearch.net/will-we-cope-if-the-rare-earths-live-up-to-their-name/ Commentary & analysis on rare earths and other technology metals Fri, 01 Apr 2011 15:10:16 +0000 hourly 1 https://wordpress.org/?v=6.4.2 By: Gareth Hatch https://www.techmetalsresearch.net/will-we-cope-if-the-rare-earths-live-up-to-their-name/#comment-1157 Fri, 01 Apr 2011 15:10:16 +0000 https://www.techmetalsresearch.net/?p=2397#comment-1157 @rukicuki: to be fair, the misconception that the addition of heavy rare-earth elements such as dysprosium and terbium, leads to an increase the Curie point of these materials (as opposed to increasing the anisotropy field and thus the intrinsic coercivity), is very common.

Dy does not have anything with the curie point either…. ohhhh

“The neodymium magnets used in hybrid cars, for example, work less well at high temperatures when recycled neodymium is used.”

Huh?

The Curie point for neo magnets isn’t anything to brag about anyway. But…what happens, does the neodymium get tired?

And I thought the reason dysprosium was added to the magnet powder was for exactly that–to boost the Curie point to a reasonable level.

As for ‘will we cope…’… could I do without my cell phone and my laptop? Keep on driving my Suburban instead of a hybrid or an all-electric? Do without wind and solar-generated power?

Where do I sign up?.
