The results of studies to determine the parameters affecting the morphology of the particle formation in certain conditions plasma chemical synthesis are present. On the example of oxides of cerium and yttrium were determined kinetic characteristics of plasmachemical process for their preparation, calculated characteristic times of the main stages occurring in the plasma-chemical reactor (t1, t2, t3, t4). Have been proposed parameter K0, characterizing the modes of hollow and solid particles formation and determining the process of salt diffusion in the droplet volume and solvent evaporate from the surface.

This paper presents a study on pulsed plasma-chemical synthesis of fluorine- and gold-doped silicon oxide nanopowder. The gold- and fluorine-containing precursors were gold chloride (AuCl3) and sulphur hexafluoride (SF6). Pulsed plasma-chemical synthesis is realized on the laboratory stand, including a plasma-chemical reactor and TEA-500 electron accelerator. The parameters of the electron beam are as follows: 400–450 keV electron energy, 60 ns half-amplitude pulse duration, up to 200 J pulse energy, and 5 cm beam diameter. We confirmed the composite structure of SixOy@Au by using transmission electron microscopy and energy-dispersive spectroscopy. We determined the chemical composition and morphology of synthesized SixOy@Au and SixOy@F nanocomposites. The material contained a SixOy@Au carrier with an average size of 50–150 nm and a shell of fine particles with an average size of 5–10 nm.

The possibility of synthesizing HTSC ceramics in the reaction chamber of a plasma-chemical reactor is shown. The method allows one to significantly reduce the process of solid-phase synthesis and obtain modified HTSC ceramics with a given content of non-superconducting additives that act as pinning centers.
