The reduction and oxidation of two-phase ceramic composites has been studied. In all cases, severe degradation of the microstructure occurs. This leads to a rapid decrease in mechanical properties, more rapid than might be expected based on the depth of microstructure changes below the gas-solid interface. The similarity and differences between the reduction of NiTiO3-TiO2 and oxidation of MgO-C and MgO-SiC composites are discussed.
