Chlorine contamination accelerates the oxidation of silicon-based ceramics through the formation of volatile silicon chloride or silicon oxychloride species which degrade the protective character of the SiO[sub 2] film. Accelerated attack may occur by active corrosion or formation of bubbles in the oxide layer. Si[sub 3]N[sub 4] is much more resistant to this attack than either silicon or SiC. This resistance may be related to the presence of a thin silicon oxynitride layer below the SiO[sub 2] scale which forms on Si[sub 3]N[sub 4].
