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 at least one oxide of a metal selected from Ti and Ta.
