The Oxidation Process in Silicon Nitrideother key silicon-based ceramic, silicon carbide. Results presented here include oxidation rates, and some effects related to the formation of a compositionally graded suboxide interlayer during the oxidation of silicon nitride. A unique, noninterfacial oxidation mechanism is shown to account for th

Oxidation Behaviour of Nitrides and Borides as Monolithic and Composite Ceramicsium nitride, titanium-diboride based monolithics and composites. Oxidation kinetics are discussed on the basis of theoretical functions which have found application in studies of reaction and/or diffusion processes occuring in the solids and the factors affecting oxidation processes are evaluated.

Corrosion and Fretting Damage of Non-Oxide Ceramics in Presence of Water Vapourcs, due to devitrification of the amorphous oxide upper layer. However few studies on the corrosion behaviour of non-oxide ceramics at low temperature (< 500 °C) in hydrothermal conditions have been carried out, though the capability of water vapour, at a temperature as low as 300 °C, to attack meta

Factors Limiting the Application of Silicon Nitride Ceramics in Sulphur-Containing Environments of Lpotentials. Under these conditions, little is known about the corrosion performance of silicon nitride ceramics. If a protective silicon dioxide layer fails to develop, corrosion might be catastrophic, since volatile silicon sulphides in addition to silicon monoxide are expected to form, leading to

Oxidation of Silicon Based Ceramics in the Presence of Alkali Halidesronments. This silica film can be fluxed by alkali oxides to form low melting alkali silicate corrosion products which do not provide protection. Alkali chlorides and other halides have sufficiently high vapor pressures that silica fluxing can occur without the formation of a condensed halide salt.

The reaction of molten sodium sulfate with the silica scale on SiC or Si.N. is best described by the acid/base theory of oxides. A highly basic sodium sulfate deposit will rapidly dissolve this acidic sil
