METHOD FOR PRODUCING A GEOMETRIC OXIDIC MOLDED BODY

摘要

The invention relates to a method for producing a geometric oxidic molded body, comprising the step of mechanically compacting a powdered aggregate introduced into the cavity of a mold to give a geometric molded precursor and the step of thermally treating the geometric molded precursor, the components of said precursor decomposing or reacting while producing gaseous components, and the powered aggregate containing metal oxides or metal oxide precursors such as nitrate or ammonium salts and the mold material being in contact with the mold bore being a hard metal of 80% by weight or more of WC and 5% by weight of nickel.
