Abstract

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 V.sub.2 O.sub.3, Fe.sub.2 O.sub.3, WO.sub.3, Co.sub.2 O.sub.3, NiO, Cr.sub.2 O.sub.3, CeO.sub.2, SnO.sub.2, CuO, MoO.sub.3, Pt, Pd, Rh, Ru, Ir and Re. The method comprising the steps of: PA0 depositing vaporized oxidized molybdenum on the oxidized titanium powder in an atmosphere of molybdenum vapor at temperatures of 460.degree. to 650.degree. C., PA0 forming a powdery mixture comprising the oxidized titanium powder with the deposited oxidized molybdenum and said active metallic component, PA0 adding water sufficient to make a viscous material of the powdery mixture, PA0 kneading the viscous material, PA0 shaping an article by using the viscous material, and PA0 calcining the article to produce a product.
