Abstract: Wall flow membrane filters, fabricated by masking a first subset of the channels at one or both ends of a honeycomb body comprising an array of open-ended through-channels separated by porous channel walls, applying a membrane-forming composition to the porous channel walls of a second subset of the channels, curing the membrane-forming composition to provide a wall-adhering fluid-permeable membrane; and then plugging the first subset of channels at a first end of the body and the second subset of channels at a second end of the body, are useful in exhaust systems of improved particulate filtration efficiency for gasoline direct injection or diesel engines.

Abstract: Methods of fabricating a glass laminate is provided. According to one embodiment, a glass laminate comprised of a microwave absorbing layer and a microwave transparent layer is formed. The microwave absorbing layer is characterized by a microwave loss tangent ?H that is at least a half order of magnitude larger than a loss tangent ?L of the microwave transparent layer. An area of the glass laminate is exposed to microwave radiation. The exposed area comprises a cross-laminate hot zone having a cross-laminate hot zone temperature profile. Substantially all microwave absorbing layer portions of the hot zone temperature profile and substantially all microwave transparent layer portions of the hot zone temperature profile reside above the glass transition temperature TG of the various layers of the glass laminate prior to impingement by the microwave radiation.

Abstract: A cement mixture suitable for use with ceramic honeycomb bodies, such as for forming an outer layer on the outer periphery of the honeycomb body, or for forming plugs in the honeycomb body. The cement mixture, when fired, preferably exhibits low coefficient of thermal expansion and high strength. The cement mixture can be applied to a green honeycomb body and simultaneously fired with the green body or can be applied to an already fired ceramic honeycomb body and then fired. Includes cement mixture comprising a plurality of inorganic components comprising talc, kaolin, alumina, silica, and aluminum hydroxide, wherein the mixture contains less than or equal to 18.0% silica and greater than or equal to 17.0% aluminum hydroxide, in percent by weight of the inorganic components.

Abstract: A method for reducing gaseous inclusions in high melting temperature or high strain point glasses is described. The method includes heating a batch material within a melting vessel to form molten glass at a melting temperature TM, the molten glass comprising a multivalent oxide material; heating the molten glass within a fining vessel to a fining temperature TF?TM; and cooling the molten glass within a refractory tube after the first or second heating step to a cooling temperature TC less than TM. The molten glass remains within the refractory tube for a time sufficient to reduce a volume of gaseous inclusions in the molten glass and cause gas species to migrate out of the gaseous inclusions into the molten glass such that at least a portion of the gaseous inclusions collapse into the molten glass.

Abstract: Feed materials are melted in a first vessel to form a glass melt at a first temperature T1, the glass melt containing at least one fining agent. The molten glass is next cooled to a second temperature T2 less than T1 in a second vessel wherein an oxygen-comprising gas is not actively added (e.g. bubbled) into the melt during the duration of the time the melt is at T2. The molten glass is thereafter heated to a third temperature T3 greater than T1 and subsequently formed into a glass article.

Abstract: A glass manufacturing system and a method are described herein for reducing gaseous inclusions in high melting temperature or high strain point glasses, such as those that are used as glass substrates in flat panel display devices. In one embodiment, the method including the steps of: (a) heating a batch material within a melting vessel to form molten glass at a melting temperature TM, the molten glass comprising a multivalent oxide material; (b) heating the molten glass within a fining vessel to a fining temperature TF?TM; and (c) cooling the molten glass within a refractory tube after the first heating step or after the second heating step to a cooling temperature TC less than TM, where the molten glass remains within the refractory tube for a predetermined resident time to reduce a volume of the gaseous inclusions in the molten glass and cause gas species to migrate out of the gaseous inclusions into the molten glass such that at least a portion of the gaseous inclusions collapse into the molten glass.

Abstract: A particulate filter is provided having a filter body with at least one porous wall, and a porous coating on the wall, the coating having a median pore diameter less than 20 microns and a coating pore size deviation of less than 3 times the coating median pore diameter, and the coating having an average thickness of less than 50 microns. A method of manufacturing a particulate filter is also disclosed which includes providing a filter body with at least one porous wall, and depositing particles onto the wall, the particles having a mean particle diameter of less than about 30 microns.
