A porous material includes aggregate particles and a binding material. In the aggregate particles, oxide films containing cristobalite are provided on surfaces of particle bodies that are silicon carbide particles or silicon nitride particles. The binding material binds the aggregate particles together in a state where pores are provided therein. The porous material contains at least one of copper, calcium, and nickel as an ancillary component.

Porous material, cell structure, and method of producing porous material

A porous material includes an aggregate in which oxide films are formed on surfaces of particle bodies, and a binding material that contains cordierite and binds the aggregate together in a state where pores are formed. The binding material or the oxide films contain a rare-earth component that excludes Ce.

Porous material, honeycomb structure, and method of producing porous material

A porous material includes aggregate particles and a binding material. In the aggregate particles, oxide films containing cristobalite are provided on surfaces of particle bodies that are silicon carbide particles or silicon nitride particles. The binding material contains cordierite and binds the aggregate particles together in a state where pores are provided therein. The mass ratio of the cordierite to the whole of the porous material is in the range of 10 to 40 mass %. The oxide films that exist between the particle bodies and the binding material have a thickness less than or equal to 0.90 &#x3bc;m.
