HONEYCOMB STRUCTURE BODY

摘要

A honeycomb structure body where honeycomb units are bound together, with seal material layers in between, and the honeycomb units each have through-holes arranged side-by-side oriented in the longitudinal direction with through-hole wall surfaces in between. The honeycomb units contain at least ceramic particles, and inorganic fibers and/or whiskers. The area of a cross-section of a honeycomb unit orthogonal to the longitudinal direction of the unit is not less than 5 cm² and not more than 50 cm², and the flatness of the outer walls of the honeycomb unit is in the range of 0.1 - 1.5 mm.
