: Spherical Fe50Ni50 alloy powders were fabricated via a novel route based on in-situ interface de-wetting between liquid Fe-Ni alloy and alumina. The obtained Fe50Ni50 alloy particles exhibit very good spherical shape according to SEM images. Furthermore, the cross-sectional SEM images show that there are no pores and bulk inclusions in the internal region of the spherical particles. The XRD results show a trace amount of the impurity alumina phase appearing in taenite phase. The size distribution agreed well with the SEM observation confirms that the alumina powders successfully segregated pre-alloy powders. As an incidental benefit, the surface alumina particles were treated as the electrical insulation coatings. The magnetic character shows that spherical Fe50Ni50 powders exhibit a good soft magnetic property even though with a slightly decreasing of saturation magnetization due to non-magnetic coatings. Our strategies provide a method to in-situ fabricate insulation coated Fe-Ni spherical alloy powders as magnetic powder core.

In this research, Silver—nickel alloy nanocomposites has been synthesized by reducing mixture solution of Ni2+, Ag+ with hydrazine hydrate as reducer and OP-10 as surfactant. Silver—nickel alloy nanocomposites were characterized by FT-IR, XRD, SEM. And the electrochemical properties of the samples were studied by cyclic voltammetry. Ag-Ni/PANI composites were prepared by in-situ synthesis and emulsion polymerization, and the effect of conduction on the conductivity was investigated including content of alloy. The detailed analysis of the synthesis conditions shows that the reduction takes place in alkaline environment and low-temperature is propitious to generate alloy solid-solution grain. Composites prepared by emulsion polymerization in acidic aqueous solutions synthesis of polyaniline shows higher conductivity than pure polymer, due to the strong interaction between alloy particles and doping PANI.
