Abstract:
1. A porous ceramic honeycomb substrate comprising: overlapped ceramic fibers, the overlapped ceramic fibers having an aspect ratio in the range of about 3 to about 1000; the overlapped ceramic fibers having a composition comprising cordierite; inorganic bonds formed between the overlapped ceramic fibers; and the substrate produced by an extrusion process comprising: mixing ceramic-material fiber with additives and a fluid to form an extrudable mixture, the additives including an inorganic binder, wherein the ceramic-material fiber comprises about 10% to about 40% of the volume of the extrudable mixture; extruding the extrudable mixture into a green honeycomb substrate; and curing the green honeycomb substrate into the porous substrate.
