FIELD: metallurgy.
SUBSTANCE: at temperature above 5500 K micro silica powder, technical propane and ammonia at a molar ratio of carbon and ammonia 1:(1.0-1.5) are introduced into a flow of nitric plasma, then they are mixed and interact; then reaction mixture is cooled first up to a temperature of 2800-3200 K, then to a temperature of 1000 K at a rate of 500000 degree/sec with the following passivation with methane acid vapors introduced into the flow at a molar ratio of silicon and methane acid 1:(0.05-0.15).
EFFECT: method allows producing silicon carbide nano powder which with its chemical, phase and granulometric composition and surface state meets component requirements which are applied to process of composite electrochemical coats and structural ceramic.
