By the mid 1990s the volatilization of silica in water vapor and the resulting rapid recession of silicon based ceramics emerged as a showstopper for the application of silicon based ceramics in combustion environments shifting the focus of coatings research to protection from water vapor mullite was found to lose silica through volatilization leaving a porous alumina layer on the surface.

Fellow of the american ceramic society. In this work the water vapor corrosion behaviors of plasma sprayed ytterbium silicate coatings with different contents of yb 2 o 3 yb 2 sio 5 and yb 2 si 2 o 7 phases were evaluated at 1400 o c for 100 300 h and the influence of phase compositions on the corrosion behaviors was analyzed.
