CIRCUMFERENCE COATING MATERIAL, BONDING MATERIAL, HONEYCOMB STRUCTURE, AND METHOD OF PRODUCING HONEYCOMB STRUCTURE
Provided is a circumference coating material that suppress a chlorine concentration and suppress an occurrence possibility of corrosion in exhaust system pipes or the like. The circumference coating material fills a recessed groove 10 that is formed on a circumferential surface 7 of a honeycomb fired body 6 and extends an axial direction at which a part of cells 3a are opened to the outside and to cover the circumferential surface, thereby forming a circumferential wall on the circumferential surface of a honeycomb structure, and the circumference coating material includes colloidal silica in a part of raw materials to be used and has a chlorine concentration of 150 ppm or less. In addition, the colloidal silica to be used has a chlorine concentration of 500 ppm or less, and the colloidal silica is produced using at least any one acid of sulfuric acid, phosphoric acid, and organic acid.
