Abstract

A ceramic body, a ceramic catalyst body, a ceramic catalyst body and related manufacturing methods are disclosed wherein a cordierite porous base material has a surface, formed with acicular particles made of a component different from that of cordierite porous base material, which has an increased specific surface area with high resistance to a sintering effect. The ceramic body is manufactured by preparing a slurry containing an acicular particle source material, preparing a porous base material, applying the slurry onto a surface of the porous base material and firing the porous base material, whose surface is coated with the slurry, to cause acicular particles to develop on the surface of the porous base material. A part of or a whole of surfaces of the acicular particles is coated with a constituent element different from that of the acicular particles.
