  • Method for making porous mullite-tialite composites
    Patent number: 8999872
    Abstract: Porous composites of acicular mullite and tialite are formed by firing an acicular mullite body in the presence of an oxide of titanium. In some variations of the process, the oxide of titanium is present when the acicular mullite body is formed. In other variations, the oxide of titanium is applied to a previously-formed acicular mullite body. Surprisingly, the composites have coefficients of linear thermal expansion that are intermediate to those of acicular mullite and tialite alone. Some of the tialite is believed to form at grain boundaries and/or points of intersection between acicular mullite needles, rather than merely coating the needles. The presence of the titanium oxide(s) during acicular mullite formation does not significantly affect the ability to produce a highly porous network of mullite needles.

  • Process for producing cemented and skinned ceramic honeycomb structures
    Patent number: 8999448
    Abstract: Organic polymer particles are provided in a cement composition that is used to apply a skin to a ceramic honeycomb, or to bond the ceramic honeycomb to another honeycomb or another material. The presence of the organic polymer particles reduces the penetration of the cement composition through porous walls of the honeycomb. In this way, less blocking of the honeycomb cells is seen, and the reduction in thermal shock performance that is often seen when cement compositions are applied to ceramic honeycombs is reduced.

  • Ceramic honeycomb filter with enhanced thermal shock resistance
    Patent number: 8999481
    Abstract: Thermal shock resistance of a ceramic honeycomb structure is increased through modifications of the cell wall joints. Wall joints can be modified such that a longitudinally-extending opening is created, putting two or more cells that meet at the wall joint in fluid communication through such opening. In such a case, all walls that meet at such a modified joint must join at least one other wall at that joint. Alternatively, wall joints can be modified by providing stress concentrating notches which extend into the joint from two or more cells that share the joint.
