Title:
ハニカム構造体及びその製造方法、並びにそれを使用した触媒体
Document Type and Number:
Japanese Patent JP4282941
Kind Code:
B2
Abstract:
The honeycomb structure (1) includes a cell structure with a number of cells (6) constituting a flow channel. An exterior wall surrounds the periphery of the cell structure. Peripheral cells (9), including the outermost cells and those positioned a set number of cells from the periphery, are sealed by the internal surface (7) of the peripheral exterior wall, at the axial end parts and/or intermediate parts, to form shield cells that obstruct the flow of fluid. The thickness of the shield cells in the radial direction of the honeycomb structure is 10% or less of the thickness of the outer diameter of the honeycomb structure. The cell structure and the external wall are made of a metallic material. An independent claim is also included for a method of manufacturing the above honeycomb structure.
