Abstract
Interaction of a
β
-SiC powder with supercritical water has been studied in the temperature range 600-800 °C under 100-500 MPa pressure. Examination of the composition of corrosion products by Raman and IR spectroscopy, XRD, SEM and TEM demonstrated that carbon and silica are formed after the hydrothermal treatment of SiC. Their structure varies depending on the experimental conditions. Amorphous and crystalline SiO
