Abstract
A method of producing a molded ceramic article comprises the first step mixing powdery raw materials and a liquid additive, thereby obtaining a mixed raw material, the second step press-molding the mixed raw material obtained in the first step in a hydrostatically applied condition of pressure, thereby removing an excess of the liquid additive to obtain a preform, and the third step calcining the preform obtained in the second step to obtain a molded ceramic article. The molded ceramic article comprises, as a principal component, copper and, as essential components, Cr and Ni within composition ranges of 0.1.ltoreq.Cr<2 wt. % and 0.1.ltoreq.Ni<10 wt. % and further at least one additive component selected from the group consisting of the following composition ratios: the following composition ratios: 0<Fe<5 wt. %, 0.ltoreq.Co<5 wt. %, 0.ltoreq.Al<10 wt. % 0.ltoreq.Ti<20 wt. %, 0.ltoreq.Mo<3 wt. %, 0.ltoreq.Si<3 wt. % 0.ltoreq.V<3 wt. % 0.ltoreq.Mg<1 wt. % and 0.ltoreq.C<5 wt. % and has at least one composition range selected from the group consisting of the following composition ratios: 0<O.sub.2 <10 wt. %, 0<N.sub.2 <5 wt. % and 0<B<10 wt. %.
