  • Method for manufacturing ceramic filter
    Patent number: 8808601
    Abstract: Honeycomb ceramic wall flow filters exhibiting reduced plug depth variability, produced by introducing flowable ceramic plugging cements into the ends of selected channels in the honeycombs and wherein the ceramic plugging cements consist of shear-conditioned mixtures exhibiting reduced viscosity differentials.
    Type: Grant
    Filed: April 29, 2009
    Date of Patent: August 19, 2014
    Assignee: Corning Incorporated
    Inventors: Michael C Brown, Luiz Eduardo Ferri, Ralph Henry Hagg, Robert Daniel Parker
  • Method of applying a cement mixture to a honeycomb body
    Patent number: 8142859
    Abstract: A method of applying a cement mixture to an exposed matrix of intersecting walls of a honeycomb body is disclosed. The method may include the steps of providing an applicator, feeding the cement mixture into applicator, forcing the cement mixture to exit the applicator with a substantially uniform velocity, while depositing the cement mixture on the exposed matrix of the honeycomb body.

  • Low shrinkage plugging mixture for ceramic filter, plugged honeycomb filter and method of manufacturing same
    Publication number: 20080307760
    Abstract: Disclosed are plugging mixtures for forming a ceramic honeycomb wall flow filter. The plugging mixtures exhibit a reduced percentage of volumetric shrinkage during the drying process and generally comprise an inorganic ceramic powder batch composition; an organic binder; a liquid vehicle; and a non-foaming volume transformation agent. Also disclosed are methods for forming plugged ceramic wall flow filters from such plugging mixtures and honeycomb articles produced therefrom.
