摘要 |
<p>A honeycomb structure 1 includes: a periphery-ground article obtained by grinding an outer peripheral portion of a cell structure 3 where a plurality of honeycomb segments 11 are bonded by means of a bonding layer 12 at an outer wall 10 of each of them, and an outer peripheral coat layer 9 disposed on an outer peripheral face 8 of the periphery-ground article; wherein at least one of the bonding layer 12 and the outer peripheral coat layer 9 is formed by the use of honeycomb-forming slurry containing:
biologically soluble fibers containing a metal oxide capable of extricating a metal ion, an inorganic binder containing a colloidal oxide having silica sol, and a chelate compound capable of multi-coordinating with the metal ion or an additive containing a first buffer solution or acid.</p> |
