Note that the powder formed by this reaction is slightly different than the Nd 2 Fe 14 B ratio. Magnets are often made both Nd rich and B rich, where finished magnets typically contain non magnetic bits of Nd and B in the grain, within which are highly magnetic Nd 2 Fe 14 B grains. For higher temperature magnet grades, additional elements are added.
