Direct Combustion Synthesis of Silicon Carbide …
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.
