    摘要: A process for preparing by a reduction/diffusion method rare earth-iron-boron alloy powders useful in permanent magnets. The process generates rare earth-iron-boron alloy powders having large and uniform particle sizes with minimal contamination. The process entails the use of a seed alloy among the starting materials, the seed alloy having substantially the same composition as the rare earth-iron-boron alloy to be prepared.
