Abstract:
The present invention provides a ceramic honeycomb structure, capable of certainly repairing the defect parts formed in the outer walls without lowering the mechanical strength or the thermal shock resistance and solving the liquid leakage trouble to the outer walls in the catalyst coating process. The ceramic honeycomb structure comprises a number of passages divided by a number of partition walls, and an outer wall dividing the passages from an outside of the honeycomb structure. A ceramic material is filled into at least one defective area on a surface of the outer wall, which has a hole of at least 0.1 mm in width communicating with the passage and the outside.
