Abstract

Purpose. The aim of this work is to study the characteristics of the plasma chemical synthesis of nanopowders of pure metals and refractory compounds. Methods. The analysis of existing methods of obtaining nanopowders. The choice of plasma chemical synthesis as the most efficient method of producing highly pure powders with a high specific surface area. The technology for producing nanopowders of Ti, V, W, Cu, Si, B and refractory compounds: TiC, TiN, Ti (C, N), SiC, B4C, VC, WC.
The application of nitrogen plasma during synthesis. Defined particle size distribution of the powders phase composition, the specific surface area is calculated. Studied crystal geometry parameters of refractory compositions, their fine structure by electron microscopy. Results. By plasma-chemical synthesis are obtained powders Ti(C,N), and SiC dispersion of 50 ... 100 nm. Determine the chemical composition of the compositions: SiC, AlN, TiC, TiN, Ti(C,N). Proved crystalline structure of the compositions, defined types of crystal lattice, their parameters. These data are consistent with the recent work on preparing particulate titanium-based powders. The generalized results of crystallographic and size-topological research nanodispersed compositions.
Scientific novelty. The peculiarities of the technology of plasma chemical synthesis in the preparation of nanosized powders range. Parameters of the synthesis process. These powders of refractory compounds of Ti (C, N) and SiC comply with the technical specifications for chemical composition. Proved crystallographic structure of the compositions. Proposed use of nanopowder compositions as modifiers for the treatment of metal melts. The practical significance. The resulting powders Ti (C, N), SiC may serve as modifiers of iron, steel, nickel, aluminum alloys.
