Abstract
The use of ceramic components in nuclear plants, pressurized turbines, chemical equipment and autoclaves for incineration of organic wastes, which are operated in supercritical water at high pressures and temperatures, has caused a wide interest in the hydrothermal corrosion of ceramics. In particular, carbon materials (glassy carbon, graphite and C/C composites) and carbides (SiC) are of interest. Studies of the stability of these materials in supercritical water at temperatures up to 1050 K have demonstrated a strong effect of their structure on the corrosion kinetics and the temperature limit for applications in water-containing environments. Dissolution of the matrix in fiber-reinforced composites can help to recover the fibers from the composite. An overview of the resistance of carbon-based materials, including carbides, to hydrothermal corrosion will be presented. Both thermodynamic analysis of possible interactions and experimental results will be presented. The effects of hydrothermal corrosion on the mechanical properties will be discussed.
