摘要：

Ultrafine Fe powders have been synthesized by mechanochemical processing. The kinetics of the formation of metallic Fe by the reduction of FeCl2 during mechanical milling has been studied. The influence of milling conditions and reductant on structure and magnetic properties was investigated. It is shown that the production of uniform nano-sized powders by mechanochemical processing requires a high particle-to-by-product ratio and avoidance of combustion by the use of low energy milling conditions or by the addition of diluents.
