Abstract: | Nickel, iron, palladium, and bimetallic nickel-palladium nanoparticles encapsulated in carbon were synthesized by contactless
levitation fusion of metals in a magnetic field in a flow of an inert gas containing a hydrocarbon. The products were characterized
by X-ray diffraction, differential thermal analysis, thermogravimetry, high-resolution transmission electron microscopy, and
adsorption. A layered carbon shell preventing agglomeration and oxidation formed on the surface of nickel- and iron-containing
particles. The size of particles depended on preparation conditions and could be of 5–15 nm.
