Abstract:
1. A method for manufacturing a ceramic honeycomb structure, comprising: kneading titania particles, alumina particles and a binder ingredient 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; drying the body comprising the raw material paste and having the honeycomb structure at a drying temperature in a range of 50° C. to 250° C. such that the body maintains a temperature difference of from 5° C. to 20° C. between a surface temperature at an outer surface of the body and a temperature at a central portion of the body and a dried body having the honeycomb structure is formed prior to sintering; and sintering the dried body having the honeycomb structure at a sintering temperature in a range of 1350° C. to 1650° C. such that a ceramic body comprising aluminum titanate and having the honeycomb structure is formed, wherein the drying of the body includes determining an output condition of heat to be applied to the body and controlling an output of heat being applied to the body based on the output condition.
