Abstract
The oxidation kinetics of reaction-sintered silicon carbide has been s tudied over the temperature range 1200-degrees to 1350-degrees-C. The material has a bulk density of 3.00 g/cm3 and the unreacted Si content is 22.5% (v/v). The activation energy for oxidation is 28.75 +/- 2.61 kcal/mol. It is proposed that the diffusion of oxygen through the gro wing oxide film is the rate-controlling process.
