BATCH COMPOSITION FOR THE MANUFACTURE OF A POROUS CORDIERITE CERAMIC ARTICLE AND METHOD FOR MAKING A POROUS CORDIERITE CERAMIC ARTICLE |
摘要 |
The present invention provides materials and methods for the manufacture of high porosity ceramic exhaust filters employing relatively low amounts of pore formers, the filters combining efficient diesel particulate filtration with effective support for exhaust emissions control catalysts. Cordierite-forming ceramic batches comprising non-hydrated transition alumina powders of relatively large particle size provide high porosities with well-controlled pore sizes and with low filter thermal expansion coefficients and good mechanical strengths. |
