COLUMNAR ALUMINUM TITANATE AND METHOD FOR PRODUCING THE SAME, AND HONEYCOMB STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a columnar aluminum titanate for producing a sintered body of honeycomb structure or the like having small thermal expansion coefficient and excellent mechanical strength, to provide a method for producing the columnar aluminum titanate and to provided a honeycomb structure formed using the columnar aluminum titanate.

SOLUTION: The aluminum titanate has an average aspect ratio (=number-average major axis length/number-average minor axis length) of ≥1.3 and has a surface on which 2-10 wt.% aluminum oxide per the columnar aluminum titanate is stuck.
