Corrosion of Silicon-Based Ceramics in Combustion Environments
TLDR
In this article, the processes of passive oxidation, deposit-induced corrosion, active oxidation, scale/substance interactions, and scale volatility are studied in the case of high-purity SiC and Si3N4 in pure oxygen, giving attention to such secondary elements in the ceramics as water and CO2 oxidants, combustion environment impurities, and thermal cycling.Abstract:
The processes of passive oxidation, deposit-induced corrosion, active oxidation, scale/substance interactions, and scale volatility are presently studied in the case of high-purity SiC and Si3N4 in pure oxygen, giving attention to such secondary elements in the ceramics as water and CO2 oxidants, combustion environment impurities, and thermal cycling. Deposit-induced corrosion is discussed for the cases of NaSO4 as well as vanadate and oxide-slag deposits; issues associated with the active-to-passive oxidation transition are noted.read more

Improvement in oxidation resistance of carbon by formation of a protective SiO2 layer on the surface
TL;DR: In this paper, solid carbon was coated with silicon dioxide (SiO2) to improve the oxidation resistance at elevated temperatures, which was carried out by exposing the carbon next to a bed of SiC powder in a flowing H2-H2O gas at 1400°C for 1 h. SiO2 was deposited on the surface of carbon via gas phase transport.
