Oxidation Behavior of Silicon CarbideERVIN1958
In a vacuum of 0.1 mm. oxidation proceeded with loss of weight because of the formation of volatile SiO 2 and at a greater rate than at atmospheric pressure. It is postulated that the rate‐controlling process in the normal oxidation of silicon carbide is the formation of solid SiO 2 on the surface.
