ZIRCONIUM OXIDE CERAMICS FOR SURFACES EXPOSED TO HIGH TEMPERATURE WATER OXIDATION ENVIRONMENTS

摘要

Disclosed is an apparatus and a process for high temperature water oxidation of combustibles in which during at least a part of the oxidation, corrosive material is present and makes contact with at least a portion of the apparatus over a contact area on the apparatus, wherein at least a portion of the contact surface area comprises a zirconia based ceramic, with the temperature of the oxidation process in excess of about 300.degree.C and the pressure of the oxidation process is in excess of about 27.5 bar (400 psi).
