"update our recent progresses toward the development of high coercivity Nd-Fe-B permanent magnets. To obtain complete understanding of the microstructure-coercivity relationships, we revisited the microstructures of Nd-Fe-B sintered and hot-deformed magnets using aberration-corrected STEM complemented by atom probe tomography (APT). We found that the structure and chemical composition of the grain boundary phase varies depending on the orientation of grain boundaries, i.e., the grain boundary phase parallel to the c-planes are mostly crystalline with a higher Nd concentration in contrast to that lying parallel to the c-axis that contains higher Fe content with an amorphous structure. Based on these new findings, we developed a method to increase the coercivity of the anisotropic Nd-Fe-B magnets substantially without relying on Dy."
Perhaps helps rationalise the bare movement of DyO pricing despite 25% of annual demand just taken out of the system, in addition to Japanese stockpiling circa 80t H2 15.
Indicative of future demand China's leading NdFeB manufacturer offers Dy Free or 50% Lite in all but three of its 67 grades: http://www.ysm-magnet.com/products/
But don't stress, George said Argus said DyO will be $400kg by next Feb, just like Jack said, Adamas said..........
Current reality is $200kg (whole box of coloured crayons can't change that), China has supply 2x demand, and NdFeB manufacturers are busy deleting or reducing it right across their magnet ranges.
Little wonder 92% TREO, 9% Dy concentrate has a net value $15.60kg on the doorstep of the Chinese separation facilities, at least those that are operating ATM.
