| description | The relevance of work is caused by the necessity to produce industrially cobalt nanopowders with specified properties. The aim of the research: to obtain cobalt nanopowder by plasmachemical synthesis, sol-gel and infrared pyrolysis methods; to determine and to compare their characteristics. Research methods: the X-ray phase qualitative and quantitative analysis, the average size calculation of coherent-scattering region and coherent-scattering region distribution by the sizes, the transmission and scanning electronic microscopy, the electron diffraction analysis, the calculation of the average size of particles with software, the method of low-temperature nitrogen adsorption, the mass spectrometry, the vibration magnetometry. The results: The authors have studied phase qualitative and quantitative compositions, disperse characteristics, morphology, magnetic properties of cobalt nanopowders obtained by three methods and have determined dimensional dependences of coercive force. It was ascertained that the nanopowders have similar morphology, but various qualitative and quantitative compositions, disperse characteristics and magnetic properties. It is impossible to interchange these materials technologically. |
