Abstract: Porous structures are made from compositions that include hollow glass bodies and an inorganic powder. The inorganic powder may act as a rigid frame member, a crystallization agent, or both, which reduces the shrinkage of the porous structures during firing. The porous structures made therefrom have an open porosity of greater than 70% and reduced shrinkage of less than 10% compared to the green structures prior to firing. Methods for firing the green structures made from the compositions are also disclosed, the firing methods including reducing a temperature ramping rate of the green structures during a crystallization temperature range of the glass of the hollow bodies.

Abstract: A method of plugging a filter, comprising: positioning a mask layer over the filter comprising a plurality of intersecting walls, wherein the intersecting walls define at least one channel between the intersecting walls; perforating the mask layer proximate the channel to form a hole, wherein the hole extends around a portion of a perimeter of the channel such that the mask layer defines a flap extending over a center of the channel; passing a plugging mixture into the channel through the hole in the mask layer; and sintering the plugging mixture to form a plug within the channel.

Abstract: A cement composition for plugging a honeycomb body, a plugged honeycomb body, and methods of plugging a honeycomb body are provided. The cement composition includes a source of inorganic particles, an inorganic binder, an organic binder, and a crosslinking agent that is capable of reacting with the inorganic binder and the organic binder. The cement composition can be dried without firing to form water-resistant plugs in a honeycomb body.
