Abstract:
1. A method for manufacturing a ceramic body having a honeycomb structure, comprising: bringing titania particles, alumina particles and a sintering additive into contact with each other such that the sintering additive, the titania particles and the alumina particles are adhered to each other and form a precursor comprising particles comprising the sintering additive, the titania particles and the alumina particles; combining the precursor with a binder material such that a raw material paste comprising the precursor and the binder material is prepared; forming a body comprising the raw material paste and having a honeycomb structure; and sintering the body having the honeycomb structure such that a ceramic body having the honeycomb structure is formed, wherein the sintering additive is mullite particles, the precursor has an amount-of-substance ratio of titania to alumina such that the ceramic body comprises titania in an amount of 22 wt. % to 40 wt. % and alumina in an amount of 59.3 wt. % to 65 wt. % with respect to an entire weight of the ceramic body, and the amount-of-substance ratio of titania to alumina in the precursor is derived based on a sum of alumina derived from the alumina particles and alumina derived from the mullite particles.
