The Reduction of Silica with Carbon and Silicon Carbide …
In the presence of carbon or silicon carbide, silica can be reacted to form a vapor of silicon monoxide. The rates of these reactions were explored at 1300° to 1550°C. For mixtures of carbon and silica, evidence supported a two‐step reaction: silicon carbide formed prior to reaction between silicon carbide and silica.
