PROBLEM TO BE SOLVED: To provide ceramics for structures with high reliability and a low cost and to provide a method for manufacturing the ceramics. SOLUTION: A mother material once dissolved in the liquid phase of a sintering aid which forms a fused liquid during sintering forms the nuclei of columnar particles during recrystallizing. While the nuclei grow, the ceramic material is sintered and forged by using a hot press tool having no restriction in the direction perpendicular to the compressing direction so as to grow the crystals into columns through the liquid phase of the sintering aid to obtain the mother material structure with controlled orientation. |
