摘要： Described herein are porous ceramic articles comprised of a porous ceramic body portion (of either predominantly open- or predominantly closed-cell porosity) having, integral with pre-selected surfaces thereof, a thin porous ceramic membrane layer which itself may be of open- or closed-celled porosity. Also described are methods of bringing about such membrane layers and such articles. The invention is particularly useful for providing porous ceramic filtering elements, such as diesel particulate traps, wherein the body portion has a predominant open-celled porosity and wherein the porous ceramic membrane surfaces also are open-celled porosity but whose pores are smaller than those of the body portion, as well as for providing articles such as kiln furniture having smooth porous ceramic membrane layers or skins on pre-selected surfaces.

摘要： Granular compositions are disclosed for use in preparing hard, water and erosion-resistant, shapes such as foundry molds and cores, that are self-setting under ambient atmospheric conditions to allow such shapes to be stripped from patterns on which they are formed, such pattern stripping being possible immediately after forming in the case of foundry cores and the like, and within controllable pattern strip times as low as 60 seconds for foundry molds. The shapes may be used without baking and, in the case of foundry molds and cores, are ready for casting molten metal within as little as one hour. Molds and/or cores free of organic materials can be formed with the novel compositions, providing essentially carbon-free surfaces at the mold-metal interface, as well as being free of other deleterious elements such as sulfur, phosphorus and boron, thereby avoiding alloy composition alteration at the interface due to migration during casting. The refractory compositions of the invention incorporate unique aluminosilicate hydrogels of alkali metals as binders, are compatible in use with existing industrial foundry mold/core-forming equipment and procedures, and are eminently free of environmental (toxicity) problems in the foundry atmosphere.
