内容: | To provide a porous ceramic formed body having many narrow pores having a pore diameter of ≤10 μm and a constant diameter and penetrating in one direction and suitable for a filter or the like and to provide its manufacturing method. ! A ceramic powder, an organic fiber having a prescribed length and diameter and an organic binder are kneaded, and the fiber is oriented in one direction by extending the kneaded matter, and a plurality of the obtained fine bar-shaped bodies are accumulated side by side in the axial direction and formed. The fiber is burnt and extinguished simultaneously with debindering by calcinating the obtained bar-shaped formed body and sintered by burning, and the bar-shaped sintered body is cut to be not more than the length of the used fiber to prepare the porous ceramic formed body having straw-shaped fine pores. The straw-shaped fine pores can be formed by dissolution with acid and impregnation at heating by using a glass fiber in place of the organic fiber. ! (C)2007,JPO&INPIT |
