China Plans to Ban Exports of Rare Earth Magnet Tech
China is considering banning the export of technologies used to produce high-performance #rare #earth #magnets deployed in electric vehicles, wind turbine motors and other products, citing “national security” as a reason, it has been learned.
With the global trend toward decarbonization driving a shift toward the use of electric motors, China is believed to be seeking to seize control of the magnet supply chain and establish dominance in the burgeoning environment sector.
China is estimated to hold an about 84% share of the global market in #neodymium magnets and an over 90% interest in #samarium #cobalt magnets.
If China bans the export of such technologies, it would be difficult for the United States and Europe, which do not traditionally manufacture rare earth magnets, to newly enter the market, thus making those countries totally dependent on China, according to a European source

@riskable ED: I was thinking that ~50 MGOe was common for #neodymium magnets, and indeed they can meet and exceed that, but it looks like most of what's on the market is well under that, esp. on the high temperature end. Ex:
https://www.arnoldmagnetics.com/products/neodymium-iron-boron-magnets/
So that makes this all the more exciting :)
-
@riskable My focus is on the #EV space. But temperature matters there too, because #neodymium magnets start to lose field strength in the range of temperatures motors actually experience (~80°C). So you have to use higher amounts of #dysprosium, which means even higher cost & somewhat lower nominal field strengths. So #tetrataenite could be a really good fit, IF the achievable field strengths can approach the theoretical.
Need to watch this space, as I have investments in some rare earth plays.
-
Hey, any #researchers (#physics, #materials science, etc) doing #research on magnetic materials [#magnetism]? I'd like your take on the prospect of #tetrataenite as an alternative to #neodymium #magnets. My understanding is that the theoretical magnetic energy product is about 80% that of available neodymium magnets, but that raises the question of how much realizable magnetic energy products might approach theoretical.
