Direct Combustion Synthesis of Silicon Carbide Nanopowder
Direct synthesis of silicon carbide (SiC) nanopowders (size 50–200 nm BET 20 m 2 /g) in Si–C system is conducted in an inert atmosphere (argon) using a self‐propagating high‐temperature synthesis (SHS) approach. A preliminary short‐term (e.g. minutes) high‐energy ball milling (HEBM) of the initial mixture which involves pure Si and C powders is used to enhance system reactivity.
