Schematic representation of the carbothermal reduction of silica to silicon carbide and carbon nanostructure formation: (a) SiO2 is reduced to SiC via a carbothermal reaction, (b) SiC nanoparticles coalesce, (c) carbon caps form on the surface of the SiC particles through precipitation and/or SiC decomposition.
