CORROSION OF A SILICA BEARING CERAMIC IN SULFUR- OXYGEN ATMOSPHERES
Experimental observations and thermodynamic calculations are described which show that formation of SiS vapor from SiO2 in a high sulfur, low oxygen atmosphere is a viable corrosion mechanism. This mechanism will become more important than the well-known decomposition of SiO2 to SiO in those sulfur-bearing atmospheres where the oxygen activity is close to the Si/SiO2 phase boundary on a volatility diagram.
