Annotation By method of IR-pyrolysis the precursor of polyacrylonitrile and compounds of cobalt and nickel metalcarbon nanocomposites were obtained, representing nanoparticles of alloy NiCo, dispersed in nanocrystalline carbon matrix. Identification of alloy nanoparticles was carried out by the values of the lattice parameter, which was determined by X-ray analysis and was 0,3533 nm (values of the lattice parameter for Ni 0,3529 nm), this corresponds intermetallics Ni0,5Co0,5. By XRD analysis it was determined that an increase in the synthesis temperature of 500 to 800 ºC leads to increase in average size of coherent dissipation of crystallite metal phase.
