Abstract
Ceramic honeycomb bodies and methods for their manufacture are provided. The ceramic honeycomb body comprises a bulk density of less than 210 g/L, a geometric surface area (GSA) greater than 93 in−1 (3.66 mm−1), a mechanical integrity factor (MIF) greater than 0.28%, and a back pressure factor (BPF) greater than 0.4 mm2.
Claims20
A ceramic honeycomb body, comprising:
- an inlet face, an outlet face, and a plurality of parallel, elongate, open-ended cells formed by a web of intersecting cell walls traversing the ceramic honeycomb body from the inlet face to the outlet face, the ceramic honeycomb body comprising a bulk density less than 210 g/L, a geometric surface area (GSA) greater than 93 in−1, and a mechanical integrity factor (MIF) greater than 0.28%.
A ceramic honeycomb body, comprising:
- an inlet face, an outlet face, and a plurality of parallel, elongate, open-ended cells formed by a web of intersecting cell walls traversing the ceramic honeycomb body from the inlet face to the outlet face, the intersecting cell walls comprising a thickness equal to or greater than 63.5 μm, the ceramic honeycomb body comprising a cell density greater than 684 CPSI and less than 1083 CPSI, a geometric surface area (GSA) greater than 95 in−1, a mechanical integrity factor (MIF) greater than 0.5%, and a backpressure factor (BPF) greater than 0.5 mm2.
