Saving the Rare Earth Elements Used In Magnets
March 3, 2011 | 2 Comments
Professor Thomas Schreflat is leading a team St. Pölten University of Applied Sciences in Austria showing that rare earth permanent magnets may contain local deformations in the crystal lattice of the material, resulting in a weakening of the magnetic force of the material in those areas. Finding ways to minimize or eliminate the deformations would […]

A New Fact Check On the Rare Earth Elements
November 24, 2010 | 3 Comments
The U.S. National Defense Authorization Act for 2010 directs the Comptroller General to complete a report on rare earth elements (REE) material. REEs are the fifteen elements with atomic numbers 57 through 71, from lanthanum to lutetium ( the lanthanides), plus yttrium, atomic number 39, which is chemically similar to the lanthanide elements and thus […]
