Abstract: A manufacturing method of a ceramic formed body, including: a mixing step in which a raw material for forming a ceramic formed body is dryly mixed, and then, a liquid is added to the obtained dry mixture to wetly mix the mixture; a kneading step in which a mixture obtained in the mixing step is kneaded; an injection step in which supercritical carbon dioxide in the state of supercritical fluid is injected into a kneaded product obtained in the kneading step; and a forming step in which a forming raw material containing the supercritical carbon dioxide obtained in the kneading step and the injection step is extruded to form the ceramic formed body.

Abstract: In a porous body, a surface layer thickness Ts takes a relatively small value satisfying P?0.54 Ts (formula (1)), the surface layer thickness Ts being derived by a microstructure analysis using the porous-body data that is prepared through three-dimensional scanning of a region including a surface (inflow plane 61) of the porous body. Here, P denotes a porosity [%] of the porous body, and 0%<P<100% and 0 ?m<Ts are assumed. The surface layer thickness Ts is derived as a distance in a thickness direction (X direction) between a surface-layer region start plane 92 in which a straight-pore opening ratio becomes 98% or less for the first time and a surface-layer region end plane 93 in which the straight-pore opening ratio becomes 1% or less for the first time.

Abstract: A manufacturing method includes: a dry mixing step of dry mixing a raw material by batch processing; a wet mixing step of adding liquid to a dry mixture obtained at the dry mixing step by continuous processing, the liquid including at least one type of water, surfactant, lubricant and plasticizer, while wet mixing; a kneading step of kneading a wet mixture obtained at the wet mixing step; and a forming step of extruding a kneaded mixture (forming raw material) obtained at the kneading step to make a ceramic formed body.

Abstract: An extrusion forming apparatus includes an extruding section, a chamber drum, and a forming section. The extruding section kneads a material including a ceramic raw material and extrudes a kneaded material. The chamber drum has a first space portion having a first extruding direction extending portion through which the kneaded material is allowed to flow in an extruding direction, and a second space portion which has a second extruding direction extending portion extending in the extruding direction and a direction changing portion bending from the extruding direction to a downward direction, to allow the kneaded material to flow in the downward direction changed from the extruding direction. The second space portion has a cross section obtained by isotropically decreasing a cross section of the first space portion perpendicular to a flow-through direction of the kneaded material. The forming section has a die to extrude a ceramic formed body.

Abstract: An apparatus of the present invention is a continuous extrusion forming apparatus comprising: a screw which carries a forming raw material in the horizontal direction, the screw being built in the screw part; and a mouth piece structure for extrusion forming, which is provided on the downstream side of a screw part, wherein the mouth piece structure has a horizontal channel for extruding the forming raw material flowing in from the screw part in the horizontal direction, an extrusion channel orthogonal to the horizontal channel, and an extrusion port provided at a tip end of the extrusion channel, and wherein a mouth piece structure holder which holds the mouth piece structure is provided with a turning means which freely changes the opening direction of the extrusion port between the horizontal direction and a floor facing direction.

Abstract: An extruder comprises an extruding section, a chamber drum, and a forming section. The extruding section kneads and extrudes a kneaded material including a ceramic raw material. The chamber drum includes a first space portion which extends from the extrusion port side of the extruding section in an extruding direction and allows the kneaded material to flow in the extruding direction, and a second space portion which extends from a downstream side of the first space portion in a downward direction, allows the kneaded material to flow in the downward direction different from the extruding direction, and has a discharge port to discharge the kneaded material. The forming section includes a die through which the kneaded material discharged through the discharge port of the chamber drum is pushed out, to extrude and form ceramic formed bodies.
