Publication number: 20080067725Abstract: A method for manufacturing a honeycomb structure having a low pressure loss and a high strength includes preparing a material composition containing a silicon carbide powder, a binder and an additive; molding the material composition to manufacture a pillar-shaped honeycomb body molded having cells disposed in parallel with one another and in a longitudinal direction; carrying out a degreasing treatment on the honeycomb molded; and carrying out a firing treatment on the honeycomb degreased body to manufacture a honeycomb fired body. The silicon carbide powder of the material composition contains a silicon carbide coarse powder and a silicon carbide fine powder having an average particle diameter (D50) smaller than that of the silicon carbide coarse powder, and the additive contains a metal oxide power. An amount of the metal oxide powder in the material composition is in the range of about 0.8 to about 4.0% by weight.Type: ApplicationFiled: July 23, 2007Publication date: March 20, 2008Applicant: IBIDEN CO., LTD.Inventors: Kazuya Naruse, Kazutomo Matsui, Kosei Tajima
