Patent number: 11919194Abstract: A method of plugging channels of a honeycomb body and a honeycomb body including plugged channels. The method includes applying a shear force to a plugging mixture including a plurality of inorganic particles, clay, and a liquid vehicle to alter the viscosity of the plugging mixture from a first viscosity prior to the vibrating to a second viscosity which is less than the first viscosity. A honeycomb body is placed into contact with the plugging mixture such that a portion of the plugging mixture having the second viscosity flows into the plurality of channels. Application of the shear force is stopped or reduced to increase the viscosity of the portion of the plugging mixture in the plurality of channels to greater than the first viscosity.Type: GrantFiled: January 29, 2021Date of Patent: March 5, 2024Assignee: Corning IncorporatedInventors: Keith Norman Bubb, Theresa Chang, Joseph Henry Citriniti, Kevin Eugene Elliott, Xinyuan Liu, Robert John Locker, Prashanth Abraham Vanniamparambil, Kevin Lee Wasson, Shu Yuan
