Synthesis of Silicon Carbide in Hypervelocity Plasma Jet

Abstract

Results of plasmodynamic synthesis of silicon carbide nanopowders are given in the article. Studies of the synthesis product by X-ray diffractometry and transmission electron microscopy indicated that the product consists mainly of cubic silicon carbide and also includes cubic silicon, ultradispersed graphite and carbon onion-like structures. It was shown that a phase composition change in the synthesis product is possible by changing the ratio of precursor mixture.
