The isothermal oxidation of mullite‐alumina‐zirconia‐silicon carbide composites obtained by reaction sintering was studied in the temperature interval 800° to 1400°C. The kinetics of the oxidation process was related to the viscosity of the surface glassy layer as well as to the crystallization of the surface film. The oxidation kinetics was halted for T ≤ 1300°C, presumably because of crystallization.
