摘要： Sintered product having a relative density of greater than 90%, with, to more than 80% of the volume thereof, a stack of flat ceramic platelets, the assembly of the platelets having a mean thickness of less than 3 μm, having a width of greater than 50 mm, and including more than 20% of alumina, as a percentage on the basis of the weight of the product. The width of the product is the largest dimension measured in the plane in which the length of the product is measured, along a direction perpendicular to the direction of the length. The length of the product is the largest dimension thereof in a plane parallel to the general plane in which the platelets extend.

摘要： A system and method to dry plug cement in a ceramic honeycomb body during the manufacture of plugged ceramic honeycomb bodies. The system includes a heating element (520) configured to immediately heat without contact a face (502) of a ceramic honeycomb body (500) plugged with a wet plug cement (510) to rapidly dry and stiffen the plug cement (510) on the face (502) of the ceramic honeycomb body (500). The method includes immediately applying heat without contact to a face (502) of a ceramic honeycomb body (500) having wet plug cement (510) disposed in channels (508) of the ceramic honeycomb body at the face, and rapidly drying and stiffening the plug cement on the face of the ceramic honeycomb body.

摘要： A method for manufacturing a ceramic article including (i) a step of irradiating a powder mainly containing a ceramic material with an energy beam to sinter or melt and solidify the powder into a solidified portion, wherein the step is repeated a predetermined number of times to sequentially bond the resulting solidified portions together to obtain a ceramic modeling object, (ii) a step of allowing the shaped ceramic object to absorb a metal component-containing liquid that contains inorganic particles containing a metal element; and (iii) a step of heating the shaped ceramic object that has absorbed the metal component-containing liquid.

摘要： On a working platform of a stereolithography machine, is manufactured, by the technique of additive manufacturing, simultaneously but separately, from a same pasty photocurable ceramic composition: a green assembly made up of a support of the green piece and of the green piece on the support, the free surface of the latter imprinted by a first face of the green piece; and a green ceramic shaper whose free surface bears the imprint of a second face of the green piece opposed to the first face; in a kiln, is placed, on the green shaper thus obtained with its imprint turned upwards, the green assembly thus obtained with its green piece turned downwards in order for it to be received in the imprint of the shaper, and the green piece thus held between the shaper and the support is subjected to debinding and to sintering.

摘要： A high-strength zirconia-alumina composite ceramic substrate suitable for semiconductor devices has been invented. It is manufactured by a procedure starting with mixing powder formula of alumina, zirconia, and a self-made synthetic additive for ball milling in an organic solvent at room temperature. The resulting mixture is homogenously dispersed and is then subjected to the steps of slurry preparation, degassing, green embryo forming, punching, calculation, and sintering to yield the final composite ceramic substrate with an excellent mechanical property of three-point bending strength>600 MPa and superior thermoelectric properties of thermal conductivity>26 W/mK, insulation resistance>1014 Ω·cm and surface leakage current (150° C.)

摘要： Described herein are methods for forming inorganic composite oxides. Such methods include combining, at a substantially constant pH of between about 5 and about 6.75 over a period of at least about 5 minutes, an acidic precursor composition and a basic composition to form a precipitate composition, wherein the acidic precursor composition comprises an alumina precursor, a ceria precursor, a zirconia precursor and optionally one or more dopant precursors; stabilizing the precipitate by increasing the pH of the precipitate composition to between about 8 and about 10; and calcining the stabilized precipitate to form an inorganic composite oxide. Also described are inorganic composite oxides formed using such methods.
