Abstract
Ultrafine Fe powders have been synthesized by mechanochemical processi ng. The kinetics of the formation of metallic Fe by the reduction of F eCl2 during mechanical milling has been studied. The influence of mill ing conditions and reductant on structure and magnetic properties was investigated. It is shown that the production of uniform nano-sized po wders by mechanochemical processing requires a high particle-to-by-pro duct ratio and avoidance of combustion by the use of low energy millin g conditions or by the addition of diluents.
