METHOD TO PRODUCE POWDERS FROM SILICON CARBIDE NANOPARTICLES COATED WITH CARBON COATING Russian patent published in 2017 - IPC C01B31/36 C01B33/29 B82B3/00 

FIELD: nanotechnology.

SUBSTANCE: mixture of precursors: monosilane, argon and acetylene, where acetylene is introduced in the amount of 2.5-15 vol.%, at initial pressure of Р₀=0.105 MPA and initial temperature of Τ₀=170°С, is exposed to thermal decomposition in process of adiabatic compression to produce the target product. Invention provides for production of silicon carbide nanoparticles with size of 10-20 nm coated with carbon coating with thickness from 2 to 20 nm.

EFFECT: high electric conductivity, possibility to control target product properties.
