Sintered cataltyic or absorbent metallic product and method for sintering metallic powders

摘要

The present invention relates to a method for sintering oxidized titanium powder and an active metallic component containing oxidized molybdenum as a binder for oxidized titanium granules. The active metallic component comprises one or more than one selected from a group consisting of V2O3, Fe2O3, WO3, Co2O3, NiO, Cr2O3, CeO2, SnO2, CuO, MoO3, Pt, Pd, Rh, Ru, Ir and Re. The method comprising the steps of: depositing vaporized oxidized molybdenum on the oxidized titanium powder in an atmosphere of molybdenum vapor at temperatures of 460 DEG to 650 DEG C., forming a powdery mixture comprising the oxidized titanium powder with the deposited oxidized molybdenum and said active metallic component, adding water sufficient to make a viscous material of the powdery mixture, kneading the viscous material, shaping an article by using the viscous material, and calcining the article to produce a product.
