Title:
HONEYCOMB STRUCTURE
Document Type and Number:
Japanese Patent JP2015174011
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a honeycomb structure which functions as a heater when applied with a voltage, as well as a catalyst carrier; and is capable of reducing the deviation in temperature distribution, having excellent resistance to thermal shock.SOLUTION: The honeycomb structure includes a honeycomb structural part 4, and a pair of electrode parts 21 disposed on the side face 5 of the honeycomb structural part 4. Each of the pair of electrode parts 21 has a belt-like shape extending in the axial direction of the cells in the honeycomb structural part 4. In the cross section orthogonal to the axial direction of the cell 2, one electrode part 21 is disposed on the opposite side of another electrode part 21 across the center of the honeycomb structural part 4. The honeycomb structural part 4 has at least one open slit 6 in the side face 5. The honeycomb structural part 4 includes a filler 7 filled in at least one of the slits 6. The filler 7 contains aggregate and a neck material. The ratio of the thermal expansion coefficient α2 of the filler 7 to the thermal expansion coefficient α1 of the honeycomb structural part 4, that is (α2/α1), is 0.6 to 1.5.
