Tetrataenite - L1[sub]0[/sub]-type FeNi

Click For Summary
SUMMARY

Tetrataenite, a mineral phase found in meteoric iron, is being synthesized commercially to replace rare earth element (REE)-based magnets. The synthesis involves mixing iron and nickel in specific ratios with a phosphorus catalyst, followed by smelting, which allows for the rapid production of tetrataenite in bulk. This innovative approach addresses the REE crisis by providing a viable alternative for magnet manufacturing.

Tetrataenite is one of the mineral phases found in meteoric iron.

Various groups are attempting to synthesize on a commercial scale to replace REE-based magnets.
