Chemical stability of high-dispersion ferromagnetic electrolytic powders

Theory, manufacturing technology, and properties of powders and fibers

“…The upper layer consisted of oleic acid and ÉD-20 epoxy resin and the lower of electrolyte -a water solution with 20-25 g/L of FeCl 2 for iron powders and 20-25 g/L FeCl 2 and 10-12 g/L of CoCl 2 for Fe-Co powders. The resulting powder was subjected to reduction annealing at 633 to 653 K [3,4]. Witness samples were produced and their magnetic properties were determined as recommended in [5,6].…”

“…They can solidify when heated and create three-dimensional structures based on chemisorbed oligomer molecules [4]: …”
