Oxidation of bulk samples of tungsten (923 K) and zirconium (773 and 873 K) by supercritical fluid Н20/С02 (molar ratio [CO₂]/[H₂O] = 0.17—0.26) at about 300 atm is studied. The formation of monoclinic WO₃, monoclinic W₁₉O₅₅, monoclinic ZrO₂, gaseous H₂, CO, CH₄, as well as amorphous carbon (on the surface of tungsten oxide), is observed. Certain differences in oxidation of tungsten and zirconium are revealed. Oxidation of tungsten with CO₂ starts only after oxide formation in reaction with H₂O. Zirconium samples can be oxidized fully, whereas oxidation of tungsten terminates due to the formation of the protective oxide layer on metal surface.
