Abstract:
1. A method for manufacturing a ceramic honeycomb structure, comprising: forming a precursor comprising particles comprising titania particles and alumina particles; kneading a binder ingredient and the particles of the precursor comprising the titania particles and the alumina particles such that a raw material paste comprising the titania particles, the alumina particles and the binder ingredient is prepared; forming a body comprising the raw material paste and having a honeycomb structure such that the body has the honeycomb structure having a plurality of through-holes extending in a longitudinal direction of the body and a plurality of partition portions formed between the through-holes; immersing each of end portions of the body in the longitudinal direction into a sealant slurry heated at a temperature in a range of from 50° C. to 100° C. such that the sealant slurry infiltrates into the through-holes at one of the end portions of the body and seals one end of each of the through-holes of the body; and sintering the body having the honeycomb structure such that a ceramic body having the honeycomb structure is formed, wherein the forming of the precursor comprises spray-drying the alumina particles onto the titania particles.
