Aluminum titanate precursor batch compositions comprising a recycled aluminum titanate component, at least a portion of the recycled aluminum titanate component being comprised of a recycled pre-reacted aluminum titanate composition or alternatively of an un-reacted green aluminum titanate precursor composition, and methods for producing aluminum titanate ceramic articles utilizing the inventive batch compositions.

Aluminum titanate batch compositions and method

Disclosed are compositions for applying to honeycomb bodies. The compositions can be used as plugging mixtures for forming a ceramic wall flow filter. Alternatively, the compositions can be used to form skin coatings on exterior portions of a honeycomb body. The disclosed compositions include an inorganic powder batch composition, an organic binder, a liquid vehicle, and a rheology modifier. The compositions exhibit improved rheological properties, including an increased yield strength and reduced viscosity under shear, which, among various embodiments, can enable the manufacture of sintered phase end plugs having reduced levels of dimple and pinhole formations in the final dried and fired end plugs as well as end plugs having relatively uniform and desired depths. Also disclosed are methods for forming end plugged ceramic wall flow filters from the plugging mixtures disclosed herein.

Compositions for applying to ceramic honeycomb bodies

Flow-through substrates, such as honeycombs, comprising certain zeolites. The flow-through substrates may be used, for example, in the removal of a heavy metal from a fluid such as a gas stream.

Flow-through substrates and methods for making and using them

Hydrophobic polymer surfaces whose level of protein binding is less than about 50-80 ng/cmare achieved by: (1) applying a coating solution composed of a solvent and a non-ionic surfactant having a HLB number of less than 5 to the surface; and (2) drying the surface to remove the solvent and thereby bring the surfactant into direct contact with the hydrophobic polymer. The combination of a low HLB number and the drying step have been found to produce low binding surfaces which can withstand multiple washes with water and/or protein-containing solutions Alternatively, the low binding surfaces can be produced by applying the non-ionic surfactant to the mold surfaces which contact molten polymer and form the polymer into a desired shape, e.g., into a multi-well plate, a pipette tip, or the like. Further, the low binding surfaces may be produced by incorporating non-soluble, non-ionic surfactants having an HLB number of less than or equal to 10 into a polymer blend prior to molding the article.

A ceramic forming batch mixture including inorganic batch materials, such as sources of alumina, titania, and silica, a pore former combination including first and second pore formers with different compositions; an organic binder; and a solvent. Also disclosed is a method for producing a ceramic article involving mixing the inorganic batch materials with the pore former combination having first and second pore formers of different composition, adding an organic binder and a solvent, forming a green body; and firing the green body. A green body having a combination of first and second pore formers with different compositions is disclosed, as are several methods for firing to produce ceramic articles such as aluminum titanate.

A ceramic forming batch mixture including inorganic batch materials, such as sources of alumina, titania, and silica, a low amount of one or more pore formers including at least one starch; an organic binder; and a solvent. Also disclosed is a method for producing a ceramic article involving mixing the inorganic batch materials with the low amount of pore former, adding an organic binder and a solvent, forming a green body; and firing the green body. A green body having a low amount of the one or more pore formers including starch is disclosed.

Methods for producing low binding surfaces

Methods for temporarily protecting a surface of a glass article by coating the surface are provided. The methods include forming a stable, hydrophobic, removable film on the surface at the end of the glass manufacturing process while the glass is still at an elevated temperature (e.g., above 175&deg; C.). The film reduces chip adhesion to the surface as a result of cutting and grinding. After cutting and grinding, the film is removed allowing the glass to be used in such processes as the manufacture of liquid crystal displays (LCDs).

Method for temporarily protecting glass articles

Hydrophobic polymer surfaces whose level of protein binding is less than about 50-80 ng/cm,are achieved by: (1) applying to a hydrophobic polymer surface a coating solution composed of a solvent and a non-ionic surfactant having a HLB number of less than 5 and at least one hydrophilic element which can extend into an aqueous solution; and (2) drying the surface to remove the solvent and thereby bring the surfactant into direct contact with the hydrophobic polymer. The combination of a low HLB number and the drying step have been found to produce low binding surfaces which can withstand multiple washes with water and/or protein-containing solutions. Alternatively, the low binding surfaces can be produced by applying the non-ionic surfactant to mold surfaces which contact molten polymer and form the polymer into a desired shape, e.g., into a multi-well plate, a pipette tip, or the like. Further, the low binding surfaces may be produced by incorporating non-soluble, non-ionic surfactants having an HLB number of less than or equal to 10 into a polymer blend prior to molding the article. Molding uses shear condition that cause the surfactant to move to the surface of a polymer product formed by the molding such that a hydrophilic part of the surfactant extends from the surface to provide a surface having low binding for proteins.

A method of providing a protective layer for a glass sheet. The protective layer provided by depositing a solution of a polymer and water on a glass sheet at a temperature high enough to provide a layer that is insoluble in water below a temperature of about 20&deg; C. The layer is soluble in water at a temperature above about 60&deg; C., so that the protective layer can be removed by rinsing in hot water.
