Abstract
A honeycomb structure includes a plurality of cells, an inorganic fiber, and an inorganic matter. The plurality of cells are disposed substantially in parallel with one another in a longitudinal direction with a cell wall therebetween. The inorganic matter forms a fixed portion in which said inorganic fibers are fixed to one another, part of the fixed portion having a fissure.
Claims38
A honeycomb structure comprising:
- a plurality of cells disposed substantially in parallel with one another in a longitudinal direction with a cell wall therebetween;
- an inorganic fiber;
- and
- an inorganic matter, said inorganic matter forming a fixed portion in which said inorganic fibers are fixed to one another, part of the fixed portion having a fissure.

A method for manufacturing a honeycomb structure comprising a honeycomb member, comprising:
- preparing a mixture containing an inorganic fiber and a raw material of an inorganic matter having a melting point lower than a melting point of said inorganic fiber;
- molding said mixture to manufacture a honeycomb molded body in which a plurality of cells are disposed substantially in parallel with one another in a longitudinal direction with a cell wall therebetween;
- heating said honeycomb molded body at a temperature lower than the melting point of said inorganic fiber and not lower than the melting point of said raw material of the inorganic matter;
- and
- cooling the heated honeycomb molded body to manufacture the honeycomb member and to introduce a fissure into a fixed portion in said honeycomb member by setting an average changing rate of temperature dropping to a normal temperature at at least about 50° C./hr and at most about 500° C./hr, the fixed portion being formed by fixing said inorganic fibers to one another by interposing said inorganic matter in said honeycomb member.
2 more elements
An exhaust gas purifying apparatus comprising:
- a honeycomb structure;
- a member for an end portion;
- and
- a casing,
- wherein
- a first member for the end portion is disposed on a side of a first pressing metal member in the casing,
- the honeycomb structure is disposed in said casing, through holes of the honeycomb structure being aligned with through holes of said first member for the end portion,
- a second member for the end portion is disposed on a side opposite to a side of said first member for the end portion, through holes of the second member for the end portion being aligned with the through holes of said honeycomb structure, and
- a second pressing metal is disposed on said second member for the end portion,
- wherein
- said honeycomb structure having a pillar shape in which a plurality of cells disposed substantially in parallel with one another in a longitudinal direction with a cell wall therebetween, comprises:
- an inorganic fiber;
- and an inorganic matter, said inorganic matter forming a fixed portion in which said inorganic fibers are fixed to one another, part of the fixed portion having a fissure.
