N1 - The work was performed using the equipment of the center for collective use "Applied physics" of NSU with the financial support of grants of the Ministry of education and science of the Russian Federation 3.5920.2017/ITR. The sample characterization was conducted within the framework of the budget project #AAAA-A17-117041710079-8 for Boreskov Institute of Catalysis.

N2 - The method of producing of nano-dimensional silicon carbide by compressing in a cyclic chemical reactor is proposed. Pyrolysis is initiated in mixtures of monosilane and hydrocarbon with argon. The resulting product is examined by X-ray diffraction and electron microscopy. It is established that the powder contains crystallites of silicon carbide with an average size of 5–12 nm. It is shown that at certain ratios of precursor concentrations in argon, the formation of carbon nanoparticles and/or graphene coating on the surface of SiC particles is also possible. The method is technological and efficient, it can be used in the production of high purity silicon carbide nanopowders and other compounds.
