CERAMIC HONEYCOMB STRUCTURE WITH APPLIED INORGANIC SKIN
A skin is applied to a ceramic honeycomb. The skin is formed by applying a skin- forming composition and drying it. The skin-forming composition includes a carrier liquid, colloidal silica and/or colloidal alumina, and an inorganic filler. The filler includes an inorganic fiber. The filler may contain low aspect ratio particles that have the same or nearly the same CTE as the inorganic fiber. The filler may include a small proportion of a low aspect ratio filler particle that has a different CTE than the inorganic filler.
