METHOD FOR MANUFACTURING ALUMINUM-TITANATE-BASED CERAMIC HONEYCOMB STRUCTURE

摘要

A method for manufacturing a ceramic honeycomb structure includes kneading titania particles, alumina particles and a binder such that a raw material paste containing the titania particles, the alumina particles and the binder is prepared, forming a body made of the raw material paste and having the honeycomb structure, and sintering the body having the honeycomb structure such that a ceramic body having the honeycomb structure and made of aluminum titanate is formed. The titania particles are secondary titania particles each comprising primary titania particles aggregated such that the secondary titania particles have a mean volume particle diameter in the range of from 5 μm to 20 μm, and the alumina particles have a mean volume particle diameter in the range of from 2 μm to 5 μm.
