Title: Manufacture of ceramic honeycomb material
Inventor: SUZUKI MASAHIKO
IPC: B28B3/20
Filed: 1987-12-18
Abstract: PURPOSE:To manufacture a material with micropore diameters and with small pore diameter unevenness by bundling ceramic extrusion raw materials containing linear removable substances along the extrusion direction in a ceramic raw material, pressing them to a given shape to turn the material into a precursor honeycomb material, and removing the substances after drying and sintering. CONSTITUTION:As a bonding material to be added to ceramic, the resin showing viscosity, fusion bonding properties and the like by heating is preferably used. Also, water, a solvent, a lubricating material and the like are added adequately and kneaded. Then, a ceramic extrusion material is formed, while removable substances are contained along the extrusion direction by the extrusion method. At that time, as the pore diameter of the honeycomb material is optionally set by the outer diameter of said removable substances, linear materials with microdiameters are used. Next, the extruded material is cut into given length and bundled to an optional quantity. Further, the bundled raw material is put into a press of a mold and pressed to manufacture a precursor honeycomb material. After the removable substances are removed from thus manufactured precursor honeycomb material, the precursor honeycomb material is fired and sintered. Such a process as drawing, dissolving, sublimation or the like is utilized for removing the removable substances according to the quality of the removable substances.
