Diane P. Dupont,Wiktor L. Adamowicznce both the transport rates of oxygen and CO/N., and their effects are considered..SiC fiber reinforced SiC matrix composites are a new class of ceramics that rely on protection by a silica film. Oxidation of fiber coatings can degrade the performance of such composites and is considered for carbon fiber coatings.

Hot Gas Corrosion of Structural Ceramicsceramics. The high corrosion resistance of SiSiC against SO. and SO. in oxidizing gases is demonstrated. Porous SiC filter material was found to withstand oxidizing regeneration without affecting its strength or gas permeability.

Applicability of Quasi Steady State Solutions for the Kinetics of Diffusion Controlled Solid State Rect for tD/X.>2, where t is time, D is diffusivity, and X is the thickness of the layer. For reaction of a particle of size a. the quasi steady state criterion is t.D/a..>2, where t. is the time required to reach unit fraction reacted.
