Abstract: A method of making a porous structure configured for use in a particulate filter includes bonding a plurality of glass bubbles to one another, and breaching the plurality of glass bubbles. Voids within individual breached glass bubbles open into one another to form cavities that extend through the porous structure.

Abstract: A cement mixture for application to a honeycomb body and a method of forming a plugged ceramic honeycomb body is provided. The cement mixture contains a plurality of inorganic particles including at least about 50% of a refractory material selected from at least one of alumina and zirconia and less than about 15% titania (by weight), a pore forming agent, an organic binder, and a liquid vehicle.

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 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.
