Abstract
The method for manufacturing a honeycomb structure includes preparing a material composition containing at least a silicon carbide powder, a binder and an additive; molding the material composition to form a pillar-shaped honeycomb molded body in which a number of cells are placed in parallel with one another in a longitudinal direction with a cell wall therebetween; carrying out a degreasing treatment on the honeycomb molded body; and carrying out a firing treatment on the honeycomb degreased body to manufacture a honeycomb fired body. The additive contains at least one kind selected from the group consisting of alumina, silica, titania, zirconia, magnesia, and a chemical composite containing any of alumina, silica, titania, zirconia and magnesia.
