摘要： Process for making graded porosity ceramics. A process for making graded porosity ceramics is described which includes the steps of placing a chosen amount of ceramic powder into a mold, compacting the ceramic powder into a green body, applying at least one sintering aid precursor to at least one chosen surface of the green body, allowing the at least one sintering aid precursor to penetrate the at least one surface within a chosen volume of the green body, heating the green body, whereby the sintering precursor generates a sintering aid, and hot pressing and sintering the heated body at a temperature whereby the green body is transformed into the sintered ceramic object.

摘要： To cement the annulus around a casing string in a well penetrating an underground formation, a column of cement slurry which is or includes a foam cement slurry is placed in the annulus and allowed to set. The amount of gas contained in the slurry and the set cement is such that the density in the cement slurry column and the cement in the annulus increases with increasing depth.

摘要： A fluorescent member includes: a plurality of fluorescent particles; an inorganic binder; and a plurality of pores. An upper surface of the fluorescent member is a light extraction surface of the fluorescent member. The plurality of pores are localized in a vicinity of at least one of the plurality of fluorescent particles in a cross section that is parallel to the upper surface of the fluorescent member and extends through the fluorescent particles and the pores.

摘要： The present disclosure provides a method of producing an insulation preform having graded porosity for an exhaust treatment component of a vehicle. The method includes obtaining a first granular insulating material having a first diameter, a second granular insulating material having a second diameter less than the first diameter, an inorganic binder, and water. The method further includes producing a slurry comprising the first granular insulating material, the second granular insulating material, the inorganic binder, and water. The slurry is introduced into a mold having at least one surface adapted for vacuum extraction. A liquid phase of the slurry is evacuated from the mold using vacuum extraction to produce a moist preform. The moist preform has graded porosity such that a greater concentration of the second insulation material is adjacent to the at least one surface than the first insulating material. The moist preform is heated to produce the insulation preform.

摘要： Disclosed is a method and system for blending a foam modifier with foaming agent online, e.g., as may be particularly useful for gypsum or cement slurries. The foam modifier comprises a fatty alcohol that is added to a gypsum or cement slurry that includes foaming agent, such as an alkyl sulfate surfactant. The fatty alcohol can be a C6-C16 fatty alcohol in some embodiments. The use of such a foam modifier can be used, for example, to stabilize the foam, reduce waste of foaming agent, improve void size control in the final product, and improve the gypsum board manufacturing process.
