CROSSLINKED GREEN BODY ARTICLES AND METHOD OF MANUFACTURING POROUS CERAMIC ARTICLES THEREFROM

摘要

A high porosity ceramic article and method of manufacturing the same and intermediate dried honeycomb green body articles are disclosed. 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.
