Scientists have found a way to make tetrataenite in a lab. If synthetic tetrataenite works in industrial applications, it could make green energy technologies significantly cheaper.
Game changer
This is why the discovery of synthetic tetrataenite is so exciting, Jonathan Hykawy says. The compound is so tough that manufacturers could make permanent magnets out of it for all but the most demanding pieces of machinery. If that happens, the US could fill a huge part of the magnet market itself, and reduce its need for certain rare earths. And it would make for a huge shift in America's relationship with China.
