Preparation of silicon-carbide nanopowder and compositions based on it using SHS azide technology
Russian Journal of Non-ferrous Metals(2015)
摘要
Combustion of the “silicon-sodium azide-ammonium hexafluorosilicate-carbon-aluminum” powder mixture in the nitrogen medium is investigated. Conditions of the self-propagating high-temperature synthesis (SHS) of the composition of the silicon carbide nanopowder with whisker silicon nitride crystals and flux, which can be used as a modifier of cast aluminum alloys and a reinforcing phase in dispersion-hardened alumomatrix composites, are determined.
