#tetrataenite — Public Fediverse posts

A rare mineral from outer space could revolutionize solar energy. It’s called tetrataenite, and it’s a super-strong magnet that can withstand high temperatures. Researchers have used it to create a new type of solar cell that can generate more power and last longer. #Tetrataenite #SolarEnergy #SpaceMineral https://www.thecooldown.com/green-tech/tetrataenite-cosmic-magnet-stone-solar/

Originally found in a #meteorite, and now finally obtained in the laboratory. #Tetrataenite is a #material that can help become independent of rare earths materials, on which #China has almost a monopoly.

ICYMI - in 2022 a research team including Lindsay Greer @Cambridge_Uni discovered a potential new method for making the #magnets used in wind turbines and electric cars (without using #RareEarths): creating #tetrataenite.

@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.
