| abstract |
The present invention relates to a geometric oxidation process comprising mechanically compacting a powdered aggregate introduced into a mold cavity to obtain a geometric molding precursor and heat treating the geometric molding precursor. A method for producing a molded article, wherein a component of the precursor is decomposed or reacted during the production of a gas component, and a powdered aggregate containing a metal oxide or a metal oxide precursor, for example, nitrate or ammonium salt, and The mold material is in contact with a mold bore, which is a hard metal of 80 wt% or more WC and 5 wt% nickel. |
