EFFECT OF MILLING ENVIRONMENT (PARAFFIN, POLYETHYLENE, POLYSTYRENE) ON PHASE COMPOSITION, SURFACE STRUCTURE AND MICROWAVE PROPERTIES OF FE POWDERS
The effect of organic milling environment type and surfactant additives on the morphology, phase composition, surface structure, magnetostatic and microwave properties of Fe powders has been studied. The presence of surfactant favors the formation of plate-like particles and decrease in the amount of carbides in the phase composition of the particles. The permeability of the composites filled with the obtained particles is governed mainly by the shape of the filler particles. For the composites filled with the plate-like particles, an organic surface layer formed by milling in the presence of surfactants is an important parameter determining the permittivity of the composites.
