<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a fired ceramic body including a metallic wire inside, preventing occurrence of cracks. <P>SOLUTION: A metallic wire (coil 11) is placed in a mold (metallic mold 21), and "a ceramic slurry having a heat-gelling characteristic or a thermosetting property" is poured into the mold. Subsequently, the ceramic slurry is hardened and dried to form a ceramic-compact-before-fired, and then, the ceramic compact is fired. In the firing process, degreasing of the ceramic compact is firstly performed, and thereafter, a temperature of the ceramic compact is increased up to "a second temperature at which the metallic wire is softened and the ceramic compact is fired" at a second heating-up rate. When the temperature of the ceramic compact reaches the second temperature, the second heating-up rate is set such that "a shrinkage percentage of the ceramic compact is smaller than or equal to a predetermined threshold shrinkage percentage", in other word, such that the softening of the metallic wire starts before the substantial start of the firing of the ceramic compact. <P>COPYRIGHT: (C)2011,JPO&INPIT |
