摘要： The present invention provides honeycomb ceramic articles and methods of manufacturing such articles having few or no defects in the outer skin. Methods for minimizing and/or eliminating cracks in thin-wall and ultra-thin-wall cordierite honeycomb articles are disclosed. Advantageously, the present invention prevents skin cracks from forming during the production of thin-wall and ultra-thin- wall cordierite honeycomb articles by optimizing skin properties such as porosity, thickness and pore size distribution.

摘要： A sintered ceramic that exhibits an average linear coefficient of thermal expansion (25-800 DEG C) below about 5.0x10 DEG C , a total porosity between the range of 20% to about 30%. Furthermore, the sintered ceramic article exhibits a pore size distribution such that at least about 86% of pores are of a pore size of less than about 2 mu m. Lastly, the ceramic article exhibits an interconnected pore structure with the pores exhibiting a generally elongated shape, i.e., the pores are predominately oriented with their long axis in the plane of the webs. This invention also relates to a method for producing a sintered cordierite ceramic article involving first compounding and plasticizing a cordierite-forming inorganic powder batch comprising a platy talc having median particle of size less than about 2 mu m, and preferably a talc morphology index greater than about 0.75. The batch further comprises at least 4% by weight of the inorganic powder batch mixture of a dispersible A12O3-forming source having a specific surface area in excess of 50m /g and one or more of the components of kaolin, calcined kaolin, silica, and corundum, each having a median particle sizes less than 5 mu m. The plasticized powder batch thus provided is next formed into a green honeycomb by extrusion through a honeycomb extrusion die and the green honeycomb is fired to a temperature and for a time sufficient to convert the green honeycomb into a crystallized cordierite ceramic article having the aforementioned properties.

摘要： A method of manufacturing a honeycomb structure is disclosed wherein a green honeycomb body having a first contour is differentially altered such that the green honeycomb body has a second contour which is wider at a first end than at a second end. In one aspect, the altering is accomplished by removing a part of the green honeycomb body, such as with a removal tool. In another aspect, the altering is accomplished by exposing different regions of the honeycomb body to different drying environments.
摘要翻译：公开了一种制造蜂窝结构体的方法，其中具有第一轮廓的绿色蜂窝体被差别地改变，使得蜂窝蜂窝体具有在第一端比第二端宽的第二轮廓。在一个方面，改变是通过去除一部分绿色蜂窝体，例如用去除工具来实现的。另一方面，改变是通过将蜂窝体的不同区域暴露于不同的干燥环境来实现的。
