Amonest the various mechanisms that have been proposed to explain the carbothermal reduction of silicon dioxide to synthesize silicon carbide (1) SiO2(s) + 3C(s) - SiC(s) + 2CO(g) only two mechanisms have been widely accepted. The first one [1-8] involves reaction of solid silicon dioxide with solid carbon to produce silicon monoxide gas and carbon monoxide gas. The silicon monoxide gas thus produced, subsequently reacts with solid carbon to produce solid silicon carbide and carbon monoxide gas.
