Abstract:
A method for manufacturing a ceramic honeycomb structure includes kneading inorganic particles and binder ingredient such that raw material paste including the inorganic particles and binder ingredient is prepared, forming a body made of the raw material paste and having a honeycomb structure such that the body has the honeycomb structure having multiple through-holes extending in the longitudinal direction of the body and multiple partitions formed between the through-holes, degreasing of the body including heating the body in atmosphere maintaining oxygen concentration of 0.2% or less in the first heating and heating the body in atmosphere having oxygen concentration which is higher than the oxygen concentration of the first heating in the second heating such that a degreased body having the honeycomb structure is formed, and sintering the degreased body having the honeycomb structure such that a ceramic body having the honeycomb structure is formed.
