HONEYCOMB STRUCTURE, HONEYCOMB FILTER FOR EXHAUST GAS PURIFICATION, AND EXHAUST GAS PURIFICATION DEVICE
The present invention aims to provide a honeycomb structured body that controls the leakage amount of particulate matter such as soot to be not higher than the regulation value even the honeycomb structured body is used at temperatures higher than 800°C, particularly temperatures not lower than 1200°C. The honeycomb structured body of the present invention includes a plurality of silicon carbide-based honeycomb fired bodies bonded with one another by adhesive layers residing therebetween, the plurality of honeycomb fired bodies each include a large number of cells longitudinally disposed in parallel with one another with a cell wall interposed therebetween, and either one end of the cell wall that surrounds the cells is sealed. The honeycomb fired bodies contains silicon carbide particles having a surface coated with a silicon-containing oxide layer. The adhesive layers contain at least alumina fibers and inorganic balloons.
