摘要： The invention describes a high porosity ceramic article and method of manufacturing the same and intermediate dried honeycomb green body articles. The article may have a total porosity of at least about fifty-five percent, above sixty percent, or even above sixty-five percent. The method of manufacture includes mixing a ceramic-forming powder, an organic pore former, water, and a crosslinker. Drying causes a condensation reaction between the pore former and the crosslinker thereby forming a network within the green body that strengthens the green body and reduces cracking. The pore former may include starch or an activated cellulose compounds. Secondary pore forming agents, such as graphite may also be included.

摘要： A honeycomb filter includes an array of interconnecting porous walls which define an array of first channels and second channels. The first channels are bordered on their sides by the second channels and have a larger hydraulic diameter than the second channels. The first channels have a square cross-section, with corners of the first channels having a shape, such as a bevel or fillet, such that the thickness, t3, of the porous walls adjoining the corners of the first channels is comparable to the thickness, t4, of the porous walls adjoining edges of the first and second channels. Embodiments having a corner fillet with a radius, Rc, are also disclosed. Embodiments wherein 0.30 t4≦Rc≦1.0 t4 exhibit combinations of low wall pressure drop and low thermal stress.
