METHOD FOR PRODUCING CONDUCTIVE CERAMICS

PROBLEM TO BE SOLVED: To provide a method for producing conductive ceramics having high productivity since a dense sintered body can be obtained by being sintered under a normal pressure.SOLUTION: One method for producing conductive ceramics includes following steps. Mixed powder formed by mixing first ZrBpowder, first SiC powder, a first sintering aid and a first organic binder together is compacted to produce a compact (S11). The compact is heated and sintered so as to be partially liquefied, to thereby produce a sintered body (S12). The sintered body is cooled (S13). The sintered body is crushed to produce raw material powder (S14). The raw material powder, at least one of second ZrBpowder, second SiC powder and a second sintering aid, and a second organic binder are mixed together to produce a molding (S15). The molding is sintered under a normal pressure (S16).
