Abstract
Disclosed is a reaction vessel used for oxidizing and decomposing equipment suitable for processing with supercritical water, and methods of manufacturing the reaction vessel. The reaction vessel comprises an oxide film containing a platinum group metal oxide, for example having a fine crystalline structure, and a high corrosion resistance in both oxidizing and reducing atmosphere. The film is formed on a surface of the vessel by performing a pyrolysis reaction in an atmosphere containing water vapor. The oxide film is comprised of at least one platinum group metal oxide selected from Ir, Ru or Rh oxide, and a platinum group metal selected from Ti and Ta.
