Patent ID: 8017067

Claim:
A method for manufacturing a honeycomb structure, comprising the steps of: providing a first base batch compound comprising inorganic constituents; providing a first batch cross-link agent; providing an aqueous vehicle; providing a first ceramic surfactant, the first ceramic surfactant selected from the group consisting of tall oil and tall oil with an amine additive; mixing the first base batch compound, the first batch cross-link agent, the first ceramic surfactant, and the aqueous vehicle to form a ceramic solution, wherein the first batch cross-link agent is capable of cross-linking with the ceramic solution; forming the first base batch compound, the first batch cross-link agent, the first ceramic surfactant, and the aqueous vehicle into a green honeycomb structure having a plurality of channels; providing a plugging compound; plugging at least one of the plurality of channels of the green honeycomb structure with the plugging compound to form a plugged, green honeycomb structure; and drying the plugged, green honeycomb structure via a drying step, thereby forming a hardened honeycomb structure.
