A ceramic support capable of supporting a catalyst comprising a ceramic body having fine pores with a diameter or width up to 1000 times the ion diameter of a catalyst component to be supported on the surface of the ceramic body, the number of the fine pores being not less than 1&#xd7;10pores per liter, is produced by introducing oxygen vacancies or lattice defects in the cordierite crystal lattice or by applying a thermal shock to form fine cracks.

Ceramic support capable of supporting a catalyst, a catalyst-ceramic body and processes for producing same

There is provided a ceramic honeycomb structure with excellent thermal shock resistance. The ceramic honeycomb structure ( ) comprises partitions ( ) arranged in a lattice forming a plurality of cells ( ) and an outer shell ( ) surrounding the perimeter of the partitions ( ), and the outer shell ( ) is provided with slits ( ) formed by cutting the outer shell ( ) in the lengthwise direction along its entire length.

Ceramic honeycomb structure

There is provided a honeycomb structural body with a lower-than-conventional heat capacity and excellent durability. A honeycomb structural body (,) having partition walls composed mainly of cordierite arranged in a honeycomb fashion is provided with fortified section (,) with a higher strength than the general section (,) at one end or both ends (,) in the direction of length of the partition walls (,). The fortified section (,) is given improved strength by having increased density with respect to the general section.
