HONEYCOMB STRUCTURE AND METHOD FOR MANUFACTURING HONEYCOMB STRUCTURE

摘要

A honeycomb structure includes cells and aluminum titanate. The cells are provided substantially in parallel with one another in a longitudinal direction of the honeycomb structure. The cells are each sealed at either one end. The aluminum titanate includes about 40% to about 60% by mass of Al2O3, about 30% to about 50% by mass of TiO2, and about 1% to about 15% by mass of (MgO+SiO2). The honeycomb structure has a porosity of about 40% to about 60% and an aperture ratio of about 55% to about 75%.
